Magnetic moments and proton resonance shifts were measured for bis (diethyldithiophosphinato) cobalt (II), Co(DTN)_2,bis (diethylthiophosphinato) cobalt (II), Co(DMN)_2 and bis (diethylthiophosphato) cobalt (II), Co(DMP)_2 in amine-CDCl_3 solutions. The results obtained were as follows : 1) Three cobalt (II) complexes were found to give the σ type contact shift and the pseudocontact shift to pyridine protons. 2) From the pseudo-contact shift of Co(DTN)_2py_2 in pyridine CDCl_3 solutions, the bond distance between cobalt and nitrogen atoms was estimated to be 2.1 Å. 3) Co(DMP)_2 was found to form very stable adduct and Co(DMN)_2 very unstable adduct with pyridine. 4) Co(DMN)_2 was found to form 1 : 2,Co(DMN)_2py_2 adduct in pyridine-CDCl_3 s...
