Abstract: Compounds Co(SH)2X22О, where SH is salicylhydrazide C6H4(OH)CONHNH2 , X is CI-, Br-, NCS-, CIO4-, NO3-, and 0.5SO42-; n is 2, 3 or 0.5, were prepared by a reaction of cobalt(II) salts with salicylhydrazide. Isolated compounds were identified by elemental analysis and characterized on the basis of thermogravimetric analysis, conductivity and magnetic measurements, and electronic and infrared absorption spectroscopy. Based on experimental data the conclusion was drawn that coordination sites of salicylhydrazide are carbonyl oxygen and primary amino nitrogen. Stereochemisky of these compounds is also discussed.
