Saint program

Manufactured by Bruker

The SAINT program is a data reduction software used for single crystal X-ray diffraction (SCXRD) experiments. It is designed to process raw diffraction data collected from SCXRD instruments and extract the necessary information for subsequent structure determination and refinement.

Single-Crystal X-ray Diffraction Measurements

Check if the same lab product or an alternative is used in the 5 most similar protocols
Single-crystal X-ray
diffraction (SCXRD) measurements were performed at room temperature
on a Bruker D8 Venture diffractometer operating at 50 kV and 1.4 mA
equipped with a Photon 3 CMOS detector, a flat graphite monochromator,
and a Mo Kα IμS 3.0 microfocus source (λ = 0.71073
Å). The raw frame data were collected using the Bruker APEX3
software package (Bruker AXS, 2015), while the frames were integrated
with the Bruker SAINT program using a narrow-frame algorithm for the
integration of the data; absorption effects were corrected using the
multi-scan method (SADABS).28 (link) Initial models
of the crystal structures were obtained with the program SHELXT-201429 (link) and refined using the program SHELXL-201430 (link) within the APEX3 software package. The atomic
displacement parameters were refined anisotropically for all atoms.
Diamond (Crystal Impact Gmbh, 2015) was used for the structure visualization.

X-ray Crystallography Data Collection and Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Crystal data were collected on a Bruker SMART APEXII CCD area-detector diffractometer using graphite monochromated Mo Kα radiation (λ = 0.71073 Å). For the crystal, X-ray data reduction was carried out using the Bruker SAINT program. The structures were solved by direct methods using the SHELXS-97 program and refinement was done using the SHELXL-97 program. Selected crystal data and data collection parameters for all the complexes are given in Table 1. X-ray data reduction, structure solution and refinement were done using the SHELXL-97 program package.49

Single Crystal Structural Analysis of 1 and 2

Check if the same lab product or an alternative is used in the 5 most similar protocols
A single crystal of 1 and 2 compound were selected, mounted onto a cryoloop, and transferred in a cold nitrogen gas stream. Intensity data were collected with a BRUKER Kappa-APEXII diffractometer with graphite-monochromated Mo-Kα radiation (λ = 0.71073 Å). Data collection were performed with APEX2 suite (BRUKER). Unit-cell parameters refinement, integration, and data reduction were carried out with SAINT program (BRUKER). SADABS (BRUKER) was used for scaling and multi-scan absorption corrections. In the WinGX suite of programs (Farrugia, 1999 (link)), the structure were solved with SHELXT-14 (Palatinus and Chapuis, 2007 (link)) program and refined by full-matrix least-squares methods using SHELXL-14 (Sheldrick, 2015 (link)). The Bilbao Crystallograhic Server (de la Flor et al., 2016 (link)) was used to compare the crystal structure of 1 measured at 200 K to others because it was recorded in a different setting.
CCDC 1844949-1844955 contain the supplementary crystallographic data for this paper. These data can be obtained free of charge from The Cambridge Crystallographic Data Centre via www.ccdc.cam.ac.uk/data_request/cif.

Single-crystal X-ray structure determination

Check if the same lab product or an alternative is used in the 5 most similar protocols
Diffraction data were collected using a single-crystal X-ray diffractometer (D8 VENTURE, Bruker) equipped with a complementary metal oxide semiconductor detector and Mo Kα X-ray source (50 kV, 1 mA). A single crystal with a diameter of ∼50 µm was mounted on a borosilicate glass needle using an adhesive. Lattice constants were determined using the SAINT program (Bruker, 2015 ▸ ) and multi-scan absorption correction was carried out using the SADABS program (Bruker, 2015 ▸ ). The initial structure model was calculated using the SUPERFLIP program based on the charge-flipping algorithm (Palatinus & Chapuis, 2007 ▸ ). Crystal structure analysis was carried out using the JANA2006 program package (Petricek et al., 2014 ▸ ) and the analysed crystal structure was visualized using the VESTA program (Momma & Izumi, 2011 ▸ ).

Synthetic procedures. Tacn (1,4,7-triazacyclononane) ligand was synthesized as described in the literature, 33, 34 following slightly modified procedures, as presented in the SI-FigureS1. Me 3 tacn (1,4,7-trimethyl-1,4,7-triazacyclononane) ligand was commercially available and used without purification. Caution! Cyanides are very toxic and must be handled with care.
IR spectra were obtained between 4000 and 250 cm -1 on a Bio-Rad FTS 165 FT-IR spectrometer on KBr pellets.
Crystallography. Suitable crystals for X-ray crystallography were directly obtained from the reaction medium. A single crystal of the compounds was selected rapidly, mounted onto a cryoloop, and transferred in a cold nitrogen gas stream. Intensity data were collected with a BRUKER Kappa-APEXII with graphitemonochromated Mo-Kα radiation (λ = 0.71073 Å). Data collections were performed with APEX2 suite (BRUKER). Unit-cell parameters refinement, integration and data reduction were carried out with SAINT program (BRUKER). SADABS (BRUKER) was used for scaling and multi-scan absorption corrections.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
