Abstract
: Foram efetuadas reações entre o heterometálico [WCl(CO)3(bipy)(HgCl)], (bipy = 2,2'-bipiridina) e tiouréias que levaram à formação de compostos do tipo [WCl(CO)3(bipy)(HgCl)L] [L = tiouréia (tu); N-metiltiouréia (mtu); N,N-dimetiltiouréia (dmtu)]. Os espectros de absorção no infravermelho mostram que a esfera de coordenação do tungstênio mantêm-se inalterada e que as tiouréias encontram-se ligadas ao átomo de mercúrio através do átomo de enxofre.
