A pyridine-based pincer-type N-heterocyclic carbene complex of Pt(II), [Pt(II)(mesCNC)CO](PF6)2 (mesCNC = 2,6-bis(1-mestylimidazol-2-ylidenyl)pyridine), displays size-selective vapochromic behavior upon exposure to small molecules with donor atoms. An acetone adduct showing a weak interaction between acetone and a C鈮 ligand is also structurally determined.
