Reaction of (Bu4N)2[Mo(mnt)3] (mnt = cis-1,2-dicyano­ethyl­ene-1,2-dithiol­ate) with [Cu2(dppa)2(MeCN)4](ClO4)2 [dppa = bis­(diphenyl­phosphino)amine] yields the polymeric heterometallic title compound, {[Cu2Mo(mnt)3(μ-dppa)2(MeCN)2]·2CH3CN} n or {[Cu2Mo(C4N2S2)3(C24H21NP2)2(C2H3N)2]·2C2H3N}. The compound exhibits a polymeric zigzag structure formed from [Mo(mnt)3]2− and [Cu2(dppa)2(MeCN)2]2+ units linked by coordination of the CN groups of the mnt ligands to the CuI centres.

The reaction between [Cu2(μ-bis­(diphenyl­phosphino)­methane)2­(MeCN)2](ClO4)2 and (Bu4N)2[ W( cis-1,2-dicyano­ethyl­ene-1,2-dithiol­ate)3] gave the title compound, {[Cu2W(C4N2S2)3(C2H3N)(C25H22P2)2]·2C4H10O·C2H3N} n. Due to the binding between a Cu atom of the binuclear copper unit [Cu2{bis(diphenylphosphino)methane}2(MeCN)]2+ and the N atoms of the buliding block [W( cis-1,2-dicyano-ethylene-1,2-dithiolate)3]2−, a one-dimensional zigzag chain structure is formed.
