Reaction of [ReBr3(CO)3]2â with aryldiazonium salts gives the Re(III) diazenide complexes [ReBr2(NNC6H4R-4)(CO)2]â. The attachment of a PhNHCS tethering group to pyridyl hydrazine generates a HYNIC related proligand which gives a stable chelated pyridyliumthiocarbazide(2â) derivative of the [Re(I)(CO)3]+ core.
