A series of hybrids with a framework constructed from {–SiW11–Ln–SiW11–}n chains and {Cu/bimpy} ribbons

Abstract

This paper reports the preparation and X-ray single crystal structures of five organic–inorganic hybrid compounds with 3D framework, [Cu2.5(bimpy)2(H2O)2][Ln(H2O)3(α-SiW11O39)]·xH2O [Ln = EuIII and x = 3.5 for (1), Ln = SmIII and x = 2.5 for (2), Ln = HoIII and x = 3.5 for (3), Ln = YIII and x = 3.5 for (4), Ln = CeIII and x = 3 for (5)] (bimpy = 3,5-bis(1-imidazolyl)pyridine). Compounds 1–5 are isostructural, showing a 3D framework featured by {–SiW11–Ln–SiW11–}n inorganic chains and {Cu/bimpy} metal–organic ribbons stemmed from Cu2+ ions and bimpy ligands. The adjacent {Cu/bimpy} ribbons are connected by two antiparallel {–SiW11–Eu–SiW11–}n chains to create a 2D layer structure, which is extended to a (3,4,4,4,6)-connected 3D framework with (4·72)(4·6·73·8)(42·53·7)(42·72·92)(42·52·67·83·10) topology through the Cu–O covalent bonds. The magnetic and electrochemical properties of compounds 1 and 2 have been studied.
