What is Synthesis, Crystal Structure and Magnetic Property of Bis(tetra-n-butylammonium) Bis(4,5-dicyanobenzene-1,2-dithiolato) Oxovanadium Complex about?

The bis(dithiolene) oxovanadium complex, namely (n-Bu 4 N) 2 [(dcbdt) 2 VO] (dcbdt = 4,5-dicyanobenzene-1,2-dithiolato), was unprecedentedly obtained from the reaction of Na 2 dcbdt and vanadium trichloride. An X-ray structure analysis indicated that [(dcbdt) 2 VO] moieties are surrounded by n-Bu 4 N cations and there was no direct interaction among these moieties. Although there was no direct interaction among them, several SÁ Á ÁH, CÁ Á ÁH and NÁ Á ÁH van der Waals contacts between n-Bu 4 N cations and [(dcbdt) 2 VO] moieties were observed. The ESR and SQUID measurement showed that the vanadium atom is in the state of V(IV) (S = 1/2) and these magnetic moments interact with each other very weakly antiferromagnetically (h = -0.371 K).
