A series of binuclear complexes of types [M2(BPT)2(H2O)4] and [M2(BPT)2L4], where H2BPT = N-benzoyl-N'-(2-hydroxyphenyl)- thiocarbamide, L = pyridine or picolines (a,(3,7), M = Cull, Coll and Nill have been synthesized. The ligand acts as a tridentate dibasic donor coordinating through carbonyl oxygen, thiocarbamido sulfur and deprotonated phenolic oxygen to yield the metal complexes in which water is replaceable by pyridine or picolines.

The magnetic and electronic spectral data indicate the complexes to he in an approximately octahedral environment, the symmetry being Oh for the Coll and D4h, for others. Crystal field parameters for the Coll and distortion parameters for the Nill complexes on the basis of proposed geometry have been calculated.
