MX-type single chain complexes with an aromatic in-plane ligand: incorporation of aromatic interactions for stabilizing the chain structure

摘要

MX-type one-dimensional complexes [Pt-IV(amp)(2)Br-2][Pt-II/IV(amp)(2)Br](2)(HSO4)(2)(SO4)(2)center dot 13H(2)O (3) and [Pt-IV(amp)(2)Br-2][Pt-II/IV(amp)(2)Br](2)(H2PO4)(6)center dot 8H(2)O (4) were synthesized as the first analogue containing only an aromatic in-plane ligand. The Pt-Br chain structures of 3 and 4 are stabilized by both the hydrogenbond network along the chain and the p-stacking via intercalated Pt(IV) complexes. Structural and spectroscopic studies indicated that both 3 and 4 form the Pt(II/IV) mixed valence state.
