Chemical Laboratories, z. H. College of Engineering and Techuology, Aligarh Muslim University, Aligarh-202 001 (India) Manuscript received 27 February 1978, revised 5 May 1979, accepted 19 May 1980 Complexes of Co(II), Ni(II) and Cu(II) with methylenebisthioacetic acid and their pyridine derivatives were prepared. Structures have been characterised on the basis of magnetic moment, electronic and infrared spectral studies. The results are in agreement with the octahedral arrangement of the coordination sphere of the metal ions studied
