acyclic Schiff bases H4L7 and H2L8, derived from 1-(pyrrol-2-yl)butane-1,3-dione and 1,3-bis(2-aminophenoxy)propane, and from pyrrole-2-carbaldehyde and 3,6-dioxaoctane-1,8-diamine, respectively are reported, together with their respective copper(II) complexes. Crystals of [Cu(H2L7)] are monoclinic; R= 0.0549 for 1 901 observed reflections. The copper is co-ordinated in the inner (N2O2) compartment with
由1-(吡咯-2-基)丁烷-1,3-二酮和1,3-双(2-氨基苯氧基)丙烷衍生的无环席夫碱H 4 L 7和H 2 L 8的合成分别报道了吡咯-2-甲醛和3,6-二氧杂辛烷-1,8-二胺,以及它们各自的铜(II)配合物。[Cu(H 2 L 7)]的晶体是单斜晶的。对于1901次观察到的反射,R = 0.0549。铜在内部(N 2 O 2)隔间中与反式配合。配体的结合方式;近似正方形平面的配位几何显示出明显的四面体形变。吡咯和醚官能团不与铜键合。在[Cu(HL 8)(O 2 CMe)]的结构中(R = 0.0363,反射4 800),两个独立分子中铜原子的配位几何是四边形八面体,两个长轴与一个乙酸氧和一个醚氧原子相连的键;一个吡咯残基不与铜配位。
