Synthesis, optical, thermal and anti-bacterial activities of semiorganic material-thiosemicarbazide cadmium(II) picrate

Semiorganic material of thiosemicarbazide cadmium(II) picrate (TSCPACd) was synthesized. Conductivity measurement was performed using conductivity meter in dimethyl sulfoxide (DMSO) (0.01 g/100 ml). TSCPACd crystallizes in the triclinic space group P-1. FTIR study was carried out in order to confirm the presence of functional groups. UV–vis–NIR spectral studies show that the crystal is transparent in the wavelength range 375–1100 nm. Thermogravimetric and differential thermal analyses reveal the thermal stability of the crystal. The anti-bacterial and anti-fungal activities of the title compound were performed by disk diffusion method against the standard bacteria E. coli, K. pneumonia, and E. faecalis and against the fungus S. aureus, Aspergillus niger and Aspergillus flavus. The compound exhibits good anti-fungal activity.
