Assembly of heterometallic V2M2S4 cubane-like clusters. Syntheses and structures of [Et4N]2[V2M2S4(OC4H8dtc)2(SPh)2](M = Cu, Ag; dtc = dithiocarbamate)
Abstract
Two V2M2S4 cubane-like cluster dianions (M = Cu, Ag) in which each distorted square pyramidal vanadium atom is chelated by a O(CH2CH2)2NCS2 group (OC4H8dtc)(dtc = dithiocarbamate) and each four-coordinate M atom linked by a terminal PhS group are prepared from an assembly system including VS43–, CuCl [or Ag(PPh3)2+], OC4H8dtc– and PhS– and are structurally characterized.
