n-C3H7, i-C3H7) have been determined by X-ray crystallography. The compounds are polymeric with copper atoms alternately bridged by two alkoxo oxygen atoms and two thiocyanate ions, except for [Cu2(i-C3H7)2NCH2CH(CH3)O}2(NCS)2] which is a discrete alkoxo-bridged dinuclear molecule. The unusual magnetic properties are discussed in relation to the crystal structures.
一系列烷氧基桥连铜 (II) 与 2-二烷基氨基乙醇和 1-二烷基氨基-2-丙醇、[Cu2(R2NCH2CH2O)2(NCS)2] 和 [Cu2R2NCH2CH(CH3)O}2(NCS)2 的络合物] (R = CH3, C2H5, n-C3H7, i-C3H7),已制备并通过红外和电子光谱以及磁化率的温度依赖性进行表征。[Cu2i-C3H7)2NCH2CH2O}2(NCS)2]和[Cu2R2NCH2CH(CH3)O}2(NCS)2]的晶体结构(R = CH3, C2H5, n-C3H7, i-C3H7)已通过 X 射线晶体学确定。除了 [Cu2(i-C3H7)2NCH2CH(CH3)O}2(NCS)2] 是一个离散的烷氧桥双核分子,这些化合物是由铜原子交替桥接两个烷氧基氧原子和两个硫氰酸根离子的聚合物. 讨论了与晶体结构相关的异常磁性。
