title: [Pt]
abstract: The intermediacy of CO/NO substitution in the condensation of [Pt(19)(CO)(22)](4-) into [Pt(38)(CO)(44)](2-) (structure shown) has been demonstrated. Two high-nuclearity carbonyl metal clusters, including one with an unprecedented nitrosyl ligand, have been synthesized and structurally characterized.
