Spectrum ir version 10

The Rast Camphor method was used to determine the molecular weights. Conductivity Bridge 305 was used to evaluate conductivity in dry DMF (dimethylformamide). The CHNS Analyzer was used to determine the percentage of the various components (C, H, and N) present: ELEMENTAR Vario EL III at STIC Kerala, the FT-IR was recorded on FT-IR; Perkin Elmer Spectrum IR Version 10.6.2 using as KBr disc India. NMR spectra were recorded in DMSO-d₆ using a JEOL400 ECZS NMR Spectrometer, and A SCIEX Triple TOF 5600 mass spectrometer was used to certify the mass spectra. The complexes in DMSO had their electronic spectra (10^-3 M, 200–800 nm) measured at room temperature using a Perkin Elmer -25 spectrophotometer. Co(II) complexes ESR spectra were captured at liquid nitrogen temperature (LNT) using a JEOL JES - FA200 ESR Spectrometer with the X and Q bands. The powder X-ray diffraction was recorded on Bruker D8 Advance Twin- Twin at STIC Kerala, India. The morphological study was examined using a JEOL JSM6510 scanning electron microscope (SEM). TGA study has determined the stability and decomposition kinetic characteristics. Thermogravimetric analyzer (Hitachi STA 7200) TGA/DTA study was carried out with N₂ flow (20 mL min^-1) and heating rate of 10 °C/min.
