ResumoVariable temperature susceptibility measurements have been made on a number of bis(N,N-dialkylmonothiocarbamato)nickel(II) complexes. The results are characteristic of ferromagnetically coupled NiII clusters. Within the range 300-80 K the susceptibilities can be fitted extremely well to a number of possible cluster models and it is not possible to distinguish the exact molecularity. ��� Measurements on one of the complexes down to liquid helium temperatures confirm the ferromagnetic behaviour and demonstrate inter- cluster interaction at very low temperatures. The magnetic behaviour of these complexes contrasts with the diamagnetism of the square planar bis(N,N-dialkyldithiocarbamato) analogues.
