The trinuclear complex trans-Pt[Mo(CO)3( /5-C5H5)]2(PhCN)2 is prepared by the reaction of two equivalents of sodium carbonylmetallate with the square planar platinum(II) complex PtCl2(PhCN)2.3 Both cis and trans isomers afford the trans trinuclear chain complex. The lability of the benzonitrile ligand in the latter can be used advantageously for cluster synthesis this will be described in the next section. 

Nickel forms organometallic clusters with three to six metal atoms. Among these some unusual structures and bonding situations occur which were mentioned in Chapter 2. The cluster chemistry of palladium is rather poor, and the outstanding features of platinum are a considerable number of trinuclear heterometallic complexes and the chimney-like structures of the clusters [Pt3(C0)g]. ...

Most of the platinum(II) clusters are limited to tetranuclear and trinuclear platinum(II) clusters, although some Pt- M complexes having metal-metal dative bonds are known (57-61). In this article, we... 

Bonding mode M3 is truly acetylenic in character, and is common in dinuclear complexes (17). It has been observed in the trinuclear platinum cluster Pt3((PEt3)4(PhCCPh)2 (151). The three Pt atoms adopt...
