Aeolos quadro qms 403 mass spectrometer

The elemental analysis of C, H, and O was carried out using a Vario EL III CHNOS Elemental Analyzer (Elementar, Langenselbold, Germany). The Cu content was determined based on edta titration in the presence of 1-(2-pyridylazo)-2-naphtol as an indicator [32 ]. Analysis for the studied compound [determined/theoretical (%)]: C 48.9/49.8; H 6.0/6.1; O 27.1/26.5; Cu 16.9/17.6. The FT-IR spectra were recorded on a Jasco FT/IR 6200 spectrophotometer (JASCO, Easton, MD, USA), in the form of KBr pellets, in the spectral range 4000–400 cm⁻¹, with resolution 1 cm⁻¹. The thermal decompositions were carried out with a Netzsch STA 449 F1 Jupiter thermoanalyzer (Netzsch-Geratebau GmbH, Selb, Germany) coupled with a Netzsch Aeolos Quadro QMS 403 mass spectrometer (Netzsch-Geratebau GmbH, Selb, Germany). Samples were heated in Al₂O₃ crucibles, in the temperature range 35–1000 °C, with the heating rate 10 °C/min in synthetic air (80% N₂, 20% O₂).

The FT-IR spectra were recorded on the Jasco FT/IR 6200 spectrophotometer (JASCO, Easton, MD, USA), in the form of KBr pellets, in the spectral range 4000–400 cm⁻¹. The UV-Vis diffuse reflectance spectra were recorded on a Jasco V-660 spectrometer (Jasco, Easton, MD, USA), in the spectral range 190–800 nm, using spectralon [44 (link)] as a standard with 100% reflectance. The thermal decompositions were carried out with the Netzsch STA 449 F1 Jupiter thermoanalyzer (Netzsch-Geratebau GmbH, Selb, Germany) coupled with the Netzsch Aeolos Quadro QMS 403 mass spectrometer (Netzsch-Geratebau GmbH, Selb, Germany). Samples were heated in corundum crucibles, in the temperature range 35–1000 °C, with the heating rate of 10 °C/min in synthetic air (80% N₂, 20% O₂). The XRPD patterns were recorded in a reflection mode on the XPert PRO MPD diffractometer (Malvern Panalytical Ltd., Royston, UK) equipped with CuKα1 radiation, a Bragg–Brentano PW 3050/65 high-resolution goniometer, and PW 3011/20 proportional point detector.

The UV-Vis diffuse reflectance spectra were recorded on a Jasco V-660 spectrometer (Jasco, Easton, MD, USA), in the spectral range 200–850 nm, using spectralon [56 (link)] as a standard with 100% reflectance. The three-dimensional fluorescence spectra were recorded on a Jasco FP-6300 spectrofluorometer (Jasco, Easton, MD, USA), with solid samples directed at an angle of 30° to the incident beam. The excitation and emission wavelength ranges were 220–640 nm and 230–740 nm, respectively. The data pitch and bandwidth were 1 nm on both monochromators. The ATR-IR spectra of the coordination compounds were recorded on a Bruker INVENIO-R spectrometer (Bruker Optik GmbH, Ettlingen, Germany) in the spectral range 4000–400 cm⁻¹. The thermal analyses were carried out with a Netzsch STA 449 F1 Jupiter thermoanalyzer (Netzsch-Geratebau GmbH, Selb, Germany) coupled with a Netzsch Aeolos Quadro QMS 403 mass spectrometer (Netzsch-Geratebau GmbH, Selb, Germany). Samples were heated in corundum crucibles up to 1000 °C, with a heating rate 10 °C∙min⁻¹ in synthetic air (20% O₂, 80% N₂) flow.
