Abstract

The synthesis and characterization of a three-dimensional inorganic-organic hybrid network [{Cu2(CA)3}{(H3O) 2(phz)3}·G]n (1; H2CA = chloranilic acid, phz = phenazine; G = 2CH3COCH3· 2H2O) is described. The crystal structure of 1 shows that the 3D network assembly is based on a combination of two types of grid-building sub-units of (6,3) topology: an anionic metal-organic coordination honeycomb grid, and a cationic hydronium-ion-mediated organic honeycomb grid. The inorganic and organic honeycomb nets are perfectly π-π-stacked, creating an infinite number of open-end channels (channel size about 8 Å in diameter). The solid framework of 1 retains its rigidity upon removal of the guest molecules under high vacuum to form compound [{Cu2(CA) 3}{(H3O)2(phz)3}]n (2) as revealed by a single-crystal X-ray diffraction analysis. Compounds [{M 2(CA)3}{(H3O)2(phz) 3}·G]n (M = Cd, 3; M = Zn, 4; M = Co, 5; G = 2CH3COCH3·2H2O) were also prepared and characterized as isostructures of 1 [crystal data for 1: Cu2(CA) 3(H3O)2(phz)3·G, trigonal, space group P31m, formula mass = 1478.86, a = 13.7593(2) Å, c = 9.1869(2) Å, V= 1506.22(5) Å3, Z = 1; crystal data for 2: Cu 2(CA)3(H3O)2(phz)3, trigonal, space group P31m, formula mass = 1326.62, a = 13.7565(4) Å, c = 9.1544(5) Å, V = 1500.3(1) Å3, Z = 1]. The magnetic-exchange coupling between the copper centers for compound 1 was analyzed on the basis of the Curie-Weiss expression and a dinuclear magnetic model. The negative values of the Weiss constant and the magnetic-exchange coupling constant indicate an anti-ferromagnetic interaction between the copper centers. (
