Reactions of (Et(4)N)[Tp*WS(3)] [Tp* is hydridotris(3,5-dimethylpyrazol-1-yl)borate] with CuSCN in MeCN in the presence of melamine afforded the title neutral dimeric cluster [Cu(4)W(2)(C(15)H(22)BN(6))(2)(NCS)(2)S(6)(C(2)H(3)N)(2)] or [Tp*W(μ(2)-S)(2)(μ(3)-S)Cu(μ(2)-SCN)(CuMeCN)](2), which has two butterfly-shaped [Tp*WS(3)Cu(2)] cores bridged across a centre of inversion by two (CuSCN)(-) anions. The S atoms of the bridging thiocyanate ligands interact with the H atoms of the methyl groups of the Tp* units of a neighbouring dimer to form a C-H···S hydrogen-bonded chain. The N atoms of the thiocyanate anions interact with the H atoms of the methyl groups of the Tp* units of neighbouring chains, affording a two-dimensional hydrogen-bonded network.
