  二烷基二硫代氨基甲酸铜（II）的磁性和结构研究

  摘要：

  一系列铜的磁化率（II）二烷基二硫代氨基甲酸酯的测量范围为4–290 K，烷基为甲基，乙基，异丙基和正丁基。与先前在二乙基衍生物中发生强铁磁相互作用的报道相反，我们没有发现该化合物存在任何显着的交换相互作用的证据。二甲基和二异丙基类似物显示弱的反铁磁相互作用。仅二烷基系列中的二正丁基衍生物显示出强磁性交换相互作用但具有反铁磁性质的证据。这种作用是由氯仿-轻质石油（α）重结晶的相所特有的，从氯仿-乙醇（β）获得的相没有这种相互作用。为了寻找α衍生物中交换相互作用的起源，其晶体结构已由单晶X确定-射线衍射法在295 K处进行最小二乘法修正，得到1 976个“已观察”反射的残差0.032。晶体是三斜晶的，P，a = 15.29（1），b = 9.963（7），c = 9.243（7）Å，α= 67.94（7），β= 82.92（7），γ = 71.55（7）°，和Z=2。铜的环境是通常的由两个双齿配体（〈Cu–S〉，2
