catena-Poly[[[[μ-bis­(diphenyl­phosphino)amine-κ2P:P′]bis­[acetonitrile­copper(I)]]-μ-(1,2-dicyano­ethyl­ene-1,2-dithiol­ato)-[(1,2-dicyano­ethyl­ene-1,2-dithiol­ato)molybdenate(IV)]-μ-1,2-dicyano­ethyl­ene-1,2-dithiol­ato] acetonitrile disolvate]

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.
