摘要
A pyridine-based pincer-type N-heterocyclic carbene complex of Pt(II),[Pt(II)(C-mes boolean AND N boolean AND C)CO] (PF6)(2) (C-mes boolean AND N boolean AND C = 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 equivalent to O ligand is also structurally determined.
