Popis:	Hydride addition to the central carbon of the S2CPCy3 chelate in [MoBr(NO)(CO)2(η2-S2CPCy3)] (1) is accompanied by loss of Br- leading to [Mo2(NO)2(CO)4{S2C(H)PCy3}2] (2), containing two fragments of “Mo(NO)(CO)2{η2-S2C(H)PCy3}” which are bridged by a sulfur atom of each S2C(H)PCy3- ligand. Crystallography and 1H NMR reveal the existence of H···S interactions which may induce the adoption of the quasicubane structure.
