every nbta3- anion connects four CdII ions to give a 2D layer, and the layers are pillared by bix ligands to generate a 3D framework with a Schlafli symbol of (3·4·63·7)(4·64·8)(43·63)(34·42·66·76·88·92). For compound 2, every nbta3- anion connects three ZnII ions to give a 2D layer structure, the 2D layers are further connected into a facinating 3D framework by biim ligands with (3,4)-connected (3·6
摘要 四种3D配位化合物,命名为[Cd3(nbta)2(bix)2(H2O)2]·H2O (1), Zn3(nbta)2(biim)3 (2), Zn6(nbta)4(btd)5 (3) 和 [Co3(nbta)2(bid)(H2O)8]·4H2O (4) (bix=1,4-双(咪唑-1-基甲基)苯, biim=1,1'-(1, 4-丁二基)双(咪唑)、btd=1,10-双(1,2,4-三唑-1-基)癸烷、bid=1,10-双(咪唑-1-基)癸烷)和H3nbta =5-nitro-1,2,3-苯三甲酸),已通过溶剂热法合成,并通过 X 射线衍射研究对其结构进行了表征。在化合物 1 中,每个 nbta3- 阴离子连接四个 CdII 离子形成一个 2D 层,这些层由 bix 配体支撑以生成具有 (3·4·63·7)(4·64·) Schlafli 符号的 3D 骨架8)(43·63)(34·4
