The crystal structure of [Zn(sac)2(py)2] has been de termined by single-crystal X-ray diffractometry. It crystallizes in the monoclinic space group C2/c with Z = 4. We propose and discuss an assignment of its IR and Raman spectra, compatible with the structural characteristics. Its thermal behavior was investigated by means of TG and DTA methods. Some comparisons with related compounds are made.

The crystal structure of the title complex, [Cd(tsac) 2 (H 2 O)], has been determined by single crystal X-ray diffraction methods. It crystallizes in the monoclinic space group C2/c (a 12.236(3), b 8.919(3), c 16.655(3) A Ê , 96.18(2) , Z 4). The molecular structure was solved from 1705 independent re¯ections with I b 2'I and re®ned to R 1 0X0489. Infrared and Raman spectra of the complex were recorded and are brie¯y discussed. Its thermal behaviour was investigated by thermogravimetry and differential thermal analysis.
