title: Structures of two haptotropic isomers generated by the sliding of 1,3,5-triene ligands on a Pd-Pd-Pd chain.
abstract: Two haptotropic isomers of [Pd3(micro3-DMVC)2(CH3CN)2][BF4]2 (DMVC=1,2-di-(E)-carbomethoxyvinylcyclopentene) were structurally determined by X-ray crystallographic analyses; a monoclinic crystal contained a symmetric sandwich complex (micro3-eta2:eta2:eta2-coordination of DMVC ligands) and a triclinic crystal contained an unsymmetric sandwich complex (micro3-eta2:eta3:eta1-coordination of DMVC ligands), where the latter are connected to each other by C-HO hydrogen bonds.
