MX-type single chain complexes with an aromatic in-plane ligand: incorporation of aromatic interactions for stabilizing the chain structure†
Abstract
MX-type one-dimensional complexes [PtIV(amp)2Br2][PtII/IV(amp)2Br]2(HSO4)2(SO4)2·13H2O (3) and [PtIV(amp)2Br2][PtII/IV(amp)2Br]2(H2PO4)6·8H2O (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 hydrogen-bond network along the chain and the π-stacking via intercalated Pt(IV) complexes. Structural and spectroscopic studies indicated that both 3 and 4 form the Pt(II/IV) mixed valence state.
