benzonitrile adduct of copper(II) trichloroacetate, [Cu(Cl3CCOO)2(PhCN)]2, was prepared and characterized. The dimeric structure was confirmed by an X-ray structural determination. This compound crystallizes in the triclinic space group P\bar1 with a=12.780(1), b=16.064(1), c=10.130(1) A; α=108.39(1), β=113.34(1), γ=81.07(1)°. The crystal consists of two crystallographically independent dimeric units. Both
制备并表征了三氯乙酸铜 (II) 的苄腈加合物 [Cu(Cl3CCOO)2(PhCN)]2。通过X-射线结构测定证实了二聚体结构。该化合物在三斜空间群 P\bar1 中结晶,a=12.780(1), b=16.064(1), c=10.130(1) A;α=108.39(1),β=113.34(1),γ=81.07(1)°。该晶体由两个晶体学独立的二聚体单元组成。两个单元都具有熟悉的二聚乙酸铜 (II) 一水合物结构,Cu-Cu 距离为 2.731(1) 和 2.732(1) A。 80-300 K 范围内的磁化率数据可以用通常的二聚体方程很好地表示-2J=224 cm-1 的单线态-三线态能量分离。化合物中苄腈的 C≡N 伸缩频率比游离配体值增加了 31 cm-1。在 X 射线晶体学和红外光谱结果的基础上,讨论了铜 (II)-苄腈键的性质。为了讨论一些类似的磁性和光谱特性......
