The adamantane structure in polynuclear Cu4S6cores: the crystal and molecular structures of Cu4[SC(NH2)2]6(NO3)4·4H2O and Cu4[SC(NH2)2]9(NO3)4·4H2O

Abstract
The compounds Cu4[SC(NH2)2]6(NO3)4·4H2O and Cu4[SC(NH2)2]9(NO3)4·4H2O have been prepared, their structures determined, and are shown to contain a central Cu4S6 core with four trigonal planar Cu atoms in the former, but only one trigonal planar Cu in the latter.
