In FJU-32,Zn（Ⅱ） is coordinated to three μ3-OH groups forming an unprecedented 1D zigzag-like double chain,and the 1D double chains are connected to four neighbouring double chains by the cpt ligands to form an extended 3D porous coordination polymer. In FJU-33,the adjacent [Zn（atrz）] 2D layers are further connected by the cpt ligands via Zn–O coordinated bonds and neighboring interlayer hydrogen-bonding interactions to give rise to an overall 3D pillared layer structure. The neutron triazole group of the cpt ligand has weaker coordination ability than the triazolate anion of atrz ligand. Furthermore,FJU-32 and FJU-33 display high thermal stability up to 300 ℃,and the solid state fluorescence reveals that two new complexes are potential optical materials.展开更多

It crystallizes in orthorhombic, space group P212121 with a = 6.8444（4）, b = 13.6329（10）, c = 15.6641（12）A°, V= 1461.60（18）A°^3, Z= 4, Dc = 2.399 g/cm^3, F（000） = 984,μ（MoKα） = 13.132 mm^-1 and T = 293（2） K. The final R = 0.0294 and wR = 0.0490 for 2325 observed reflections with I 〉 2σ（I）. Each bismuth atom in the present compound is coordinated by six chlorine atoms to furnish a slightly distorted octahedral geometry. It is worthy to note that each adjacent [BiCl6]^3- and [H3dien]^3＋ entities are linked by hydrogen bonds to form two right- and left-handed helical double-chains running along the b axis. These two helical double-chains are interlaced into quadruple-stranded braid to give rise to a three- dimensional network. The optical absorption spectrum of the compound reveals the appearance of a sharp optical gap of 3.30 eV.展开更多
