2′-Bipy)(H2O)2⋅2H2O]n (2), [Cd(HL-As)(4,4′-Bipy)0.5]n (3), [Cd(HL-As)(2,2′-Bipy)(H2O)⋅H2O]n (4) (H3L-As = 2-(carboxymethylamino)phenylarsonic acid; 4,4′-Bipy = 4,4′-bipyridine; 2,2′-Bipy = 2,2′-bipyridine). We demonstrate that N-donor co-ligands significantly affect the coordination environment of metal centers and the structure of these compounds. Compound 1 is a three-dimension (3D) hydrogen-bond network
近年来,具有可调结构的金属有机框架(MOF)或配位聚合物(CP)的设计和构建引起了人们的极大兴趣,因为它们具有有趣的结构多样性和潜在的应用。混合配体方法被广泛用作制造CP的有效合成方法。通过精确调控N-供体共配体的结构,本工作成功合成了一系列锌/镉-有机砷酸盐,即[Zn 2 (OH)(L-As)(4,4′- Bipy)⋅H 2 O] n ( 1 ), [Zn 3 (L-As) 2 (2,2′-Bipy)(H 2 O) 2 ⋅2H 2 O] n ( 2), [Cd(HL-As)(4,4′-Bipy) 0.5 ] n ( 3 ), [Cd(HL-As)(2,2′-Bipy)(H 2 O)⋅H 2 O] n ( 4 ) (H 3 L-As = 2-(羧甲基氨基)苯胂酸;4,4'-Bipy = 4,4'-联吡啶;2,2'-Bipy = 2,2'-联吡啶)。我们证明 N 供体共配体显着影响金属
