act as Lewis acids and form complexes with bases. The Lewis acids and their complexes with various bases have been characterized by elemental analyses, molar conductance, molecular weight, magnetic moment, infrared and electronic spectral studies. These studies reveal that both the Lewis acids are monomers. In (SCN)2Co(NCS)2Hg2R2 the CO(II) has tetrahedral geometry, where as in (SCN)2Ni(NCS)2Hg2R2 the
摘要对甲苯基硫氰酸汞和α-萘基硫氰酸汞与Co(NCS)22py反应形成式(py)2(SCN)2Co(NCS)2Hg2R2的双金属粉红色化合物(R =对甲苯基和α-萘基)。在真空中加热该化合物时,形成蓝色化合物(SCN)2 Co(NCS)2 Hg 2 R 2。镍类似物(SCN)2Ni(NCS)2Hg2R2通过对甲苯基或α-萘基硫氰酸汞与硫氰酸镍的直接反应形成。(SCN)2Co(NCS)2Hg2R2和(SCN)2Ni(NCS)2Hg2R2充当路易斯酸并与碱形成络合物。路易斯酸及其与各种碱的配合物已通过元素分析,摩尔电导,分子量,磁矩,红外和电子光谱研究进行了表征。这些研究表明两种路易斯酸都是单体。在(SCN)2Co(NCS)2Hg2R2中,CO(II)具有四面体几何形状,其中(SCN)2Ni(NCS)2Hg2R2中的Ni(II)通过与其他分子的SCN-基团的轴向键合而具有八面体几何形状。化合物中存在R-Hg-SCN-M型[M
