Four new metal-organic frameworks were synthesized based on the N-donor ligand 1,5-bis(3,5-dimethylpyrazol-1-yl)-3-selenapentane (L) novel in this field of chemistry: three one-dimensional metal-organic frameworks based on silver(I) cations, [Ag3(L)2(NO3)2]-NO3·MeOH (1), [Ag(L)]NO3 (2), and [Ag(L)(H2O)]NO3 (3), and one three-dimensional metal-organic framework [Zn3(bdc)3(L)]·0.5 MeOH (4, H2bdc is 1,4-benzenedicarboxylic acid). Compounds 1 and 4 contain trinuclear units. In compound 1, these units are linked via the ligand L to form polymer chains. In compound 4, the ligand L bridges polymer layers, which are composed of carboxylate units {Zn3(bdc)6}, to form a three-dimensional framework. Compounds 2 and 3 are composed of mononuclear units, which are connected via the ligand L to form polymer chains. Luminescence of compound 3 was found to be due to intraligand transitions.

基于 1,5-双(3,5-二甲基吡唑-1-基)-3-硒戊烷的金属有机骨架:合成、结构和性质

基于该化学领域新颖的N-供体配体1,5-双(3,5-二甲基吡唑-1-基)-3-硒戊烷(L)合成了四种新型金属-有机骨架:三种一维金属-基于银 (I) 阳离子、[Ag3(L)2(NO3)2]-NO3·MeOH (1)、[Ag(L)]NO3 (2) 和 [Ag(L)(H2O) 的有机骨架]NO3 (3) 和一个三维金属有机骨架 [Zn3(bdc)3(L)]·0.5 MeOH(4,H2bdc 是 1,4-苯二甲酸)。化合物 1 和 4 含有三核单元。在化合物 1 中,这些单元通过配体 L 连接形成聚合物链。在化合物 4 中,配体 L 桥接由羧酸盐单元 {Zn3(bdc)6} 组成的聚合物层,形成三维框架。化合物2和3由单核单元组成,它们通过配体L连接形成聚合物链。
