water oxygen and three phosphinic acid oxygen atoms, the phosphinic acid group of one dapa ligand being coordinated to two copper atoms. Compound CuCl3(H·depo) was found to have a distorted tetrahedral chromophore containing the three chlorine and an amine nitrogen as donor atoms. A crystal structure determination was performed on (CuCl2)3(dmpo)4; tetragonal, space group P 4 21c, a = b = 15.330(2), c
摘要三种配体分别为:d-二甲基氨基甲基-P-苯基次膦酸dapa,P-(N,N-二甲基氨基乙基)-P,P-二苯基膦氧化物,depo和PN,N-二甲基氨基甲基)-P,P-二苯基膦氧化物,dmpo ,准备好了。分离铜配合物并进行表征。Cu(dapa)2·H2O的配位域分配为扭曲的八面体对称性,该对称性由两个胺氮,一个水氧和三个次膦酸氧原子组成,一个dapa配体的次膦酸基团与两个铜原子配位。发现化合物CuCl3(H·depo)具有扭曲的四面体发色团,该发色团包含三个氯和一个胺氮作为供体原子。对(CuCl 2)3(dmpo)4进行晶体结构测定;四边形,空间群P 4 21c,a = b = 15.330(2),c = 13.992(4)A,Z = 2。该化合物由两个五配位[Cu(dmpo)2Cl] +阳离子和一个四边形扭曲的CuCl42-阴离子组成。阳离子发色团的对称性高度扭曲,呈方形锥体状,供体原子
