Trinuclear and hexanuclear platinum clusters as building blocks for organometallic one-dimensional structures

The reaction between the new hexa- and trinuclear clusters {Pt6}(CC–C6H4–CCH)2, (4)[{Pt6}= Pt6(CO)4((mu)PBut2)4], and {Pt3}Cl, (6)[{Pt3}= Pt3((mu)-PBut2)3(CO)2], in CuI/Amine gives the thermally and air stable {Pt6} (CC–C6H4–CC{Pt3})2(7), where the cluster units are separated by conjugated 1,4-diethynylphenyl groups
