Reactions of [WCl(CO)3(bipy)(HgCl)], [bipy = 2,2’-bipyridine], with thioureas were performed giving compounds of the type [WCl(CO)3(bipy)(HgCl)], [L= thiourea (tu); N-methylthiourea (mtu); N,N-dimethylthiourea (dmtu)] in which the coordination sphere of the tungsten atom remained unchanged. The coordination of the thioureas to mercury atom was proved to occur, in accord to infrared spectra, through the sulphur atom.
