{[Cu2Mo(C4N2S2)3(C2H3N)(C25H22P2)2].-2C4H10O.C2H3N}n

The reaction between [Cu2(mu-dppm)(2)(MeCN)(2)](ClO4)(2) and (Bu4N)(2)[Mo(mnt)(3)], where dppm is bis(diphenylphosphino)-methane and mnt is cis-1,2-dicyanoethylene-1,2-dithiolate, gave the title compound, catena-Poly[[[acetonitrilebis[mu-bis-(diphenylphosphino) methane-kappa P-2: P'] dicopper(I)]-mu-(1,2-dicyanoethylene-1,2-dithiolato)-[(1,2-dicyanoethylene-1,2-dithiolato) molybdenum(IV)]-mu-( 1,2-dicyanoethylene-1,2-dithiolato)] diethyl ether disolvate acetonitrile solvate]. The binding between a Cu atom of the binuclear copper unit [Cu-2(mu-dppm)(2)(MeCN)](2-) and two N atoms of the building block [Mo(mnt)(3)](2-) results in the formation of a one-dimensional zigzag chain structure.
