The compound mu-N,N'-diphenylformamidinato-bis [2,2',2''-terpyridinepl
atinum(II)] perchlorate monohydrate (1) is formed by reaction of diphe
nyl-formamidine and [Pt(tpy)Cl]Cl (tpy = terpyridine) in the presence
of excess base. The two platinum centers are bridged by a single diphe
nylformamidinato ligand with the remaining coordination geometry compl
eted by the terpyridine group. The platinum-platinum separation is 3.0
49 (1) angstrom.
