Unique structural topologies involving metal–metal and metal–sulfur interactions: salts of [Ni(C3S5)2]x− with cis-anti-cis-dicyclohexyl-18-crown-6 complexed counter ions
Abstract
Preparation by electrocrystallisation has been carried out for the salts [Rb(anti-dchyl-18c6)]2[Ni(dmit)2] 1, [Rb(anti-dchyl-18c6)][Ni(dmit)2] 2, [Cs(anti-dchyl-18c6)]2[Ni(dmit)2] 3 and [Cs(anti-dchyl-18c6)1.5][Ni(dmit)2]64 (anti-dchyl-18c6 = cis-anti-cis-dicyclohexyl-18-crown-6, dmit = C3S5). Salts 1 and 3 involve the planar dianionic nickel complex sandwiched by two metal–
