A heterobimetallic cumulenic μ-carbido complex

The reaction [W(CSe)(CO)2(Tp*)]NEt4 (Tp* = hydrotris(dimethylpyrazolyl)borate) with N-methyl-N-nitroso-4-toluenesulfonamide affords the nitrosyl complex [W(CSe)(CO)(NO)(Tp*)] which on treatment with excess [Re(THF)(CO)2(η-C5H5)] affords the cumuenic μ-carbido complex [WRe(μ-C)(CO)3(NO)(Tp*)(η-C5H5)] in addition to the μ-selenido complex [Re2(μ-Se)(CO)4(η-C5H5)2].
