从M(NH(2))(2)和RSH之间的反应合成了一系列碱土金属硫醇盐M(SR)(2)(M = Ca,Sr,Ba)。对于R = CMe(3),产物仅微溶于吡啶,但R = 1-金刚烷基的Ca衍生物可溶,而R = CEt(3)的Ca和Sr衍生物在吡啶中的溶解度很高。所有的R = SCMe(3)衍生物溶解在1-甲基-2-吡咯烷酮(NMP)中。还制备了一种硫醇钇((Et(3)SC)(2)Y(&mgr; -SCEt(3))Py(2))(2),并通过单晶X射线衍射进行了表征。 (Sr(&mgr; -SCEt(3))(2)(NH(3))Py)(n)。前者结晶为具有平面(YS)(2)环的离散二聚体,后者形成通过硫醇盐桥连接的Sr原子无限链。晶体数据:((Et(3)SC)(2)Y(&mgr; -SCEt(3))Py(2))(2)P&onemacr ;, a = 11.592(1)Å,b = 17.328(2)Å
