Visit Supplier

The AXS Smart APEX II CCD X-diffractometer is a laboratory instrument designed for single-crystal X-ray diffraction analysis. It utilizes a charge-coupled device (CCD) detector to collect diffraction data from crystalline samples. The core function of this product is to determine the atomic and molecular structure of crystalline materials through the analysis of their X-ray diffraction patterns.

Data
collection of compound 1 was performed on a Bruker AXS
Smart APEX II CCD X-diffractometer equipped with graphite monochromated
Mo Kα radiation (λ = 0.71073 Å) at 293 ± 2 K.
An empirical absorption correction was applied using the SADABS program.
The structure was resolved by direct methods and refined by full matrix
least-squares fitting on F2 by using SHELXS-2014.68 (link) All non-hydrogen atoms were refined anisotropically.
The hydrogen atoms of organic ligands were located geometrically and
with fixed isotropic thermal parameters. The hydrogen atoms for the
solvent water molecules excepting O1W were located through Fourier
electron density. The solvent water molecule (O1W) and carboxyl oxygen
atom (O4) were disordered, which were split over two sites and refined
with partial occupancy. Crystal data and structure refinements of
compound 1 are summarized in Table S1. Bond distances and angles of compound 1 are
listed in Table S2.

The crystals were grown by slow evaporation from methanol solution for 3a. Data collections were performed on the Bruker AXS Smart APEX II CCD X–diffractometer using filtered Mo-Kα radiation (λ = 0.71073 Å) at 296 ± 2 K. The crystal structure was solved by direct method and refined by full–matrix least squares fitting on F2 by SHELXS–97. The non–hydrogen atoms were refined anisotropically. The crystallographic data have been deposited at the Cambridge Crystallographic Data Centre, reference number CCDC1444192.

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.
