Abstract The synthesis and crystal structures of five new analogues of the supramolecular copper(II) organophosphonate [CuII(phen)2Cl][(C6H5PO(OH)2)((OH)O2PC6H5)] (1) are presented. The structures contain substituted phenylphosphonic acids, and are of the general formula [CuII(phen)2Cl][(XPO(OH)2)((OH)O2PX)] · Z, where X = o-CH3(C6H5) (2); X = p-CH3(C6H5), Z = H2O · 2CH3CH2OH (4); X = o-NO2(C6H5),
摘要介绍了五种超分子有机膦酸铜(II)[CuII(phen)2Cl] [(C6H5PO(OH)2)((OH)O2PC6H5)](1)的合成和晶体结构。该结构包含取代的苯基膦酸,并且具有通式[CuII(phen)2Cl] [(XPO(OH)2)((OH)O2PX)]·Z,其中X = o-CH3(C6H5)(2) ; X =对-CH 3(C 6 H 5),Z = H 2 O·2CH 3 CH 2 OH(4); m = 1。X =邻-NO2(C6H5),间-NO2(C6H5)(5); X =间-NO 2(C 6 H 5)(6); X = C 10 H 7(7)。单晶分析揭示了与1相似的分子单元的结构,除了4包含晶格溶剂。1、2、4、5和6保持某种形式的[CuII(phen)2Cl] +阳离子与二聚H键合的阴离子酸“链”交错的“条带”的一般组装策略。发现对堆积的扰动主要与取代基的位置有关(而不是化
