ligand (6,6′-(2,4,6-triisopropylphenyl)-2,2′-bipyridine), and the syntheses, structures, and magnetic properties of the first coordination compounds based on this ligand are described. Tripbipy was synthesized by the Suzuki coupling of 2,4,6-triisopropylphenyl boronic acid and 6,6′-dibromo-2,2′-bipyridine. Reported here are the tripbipy complexes of five late first row transition metal chlorides (MCl2;
三联吡啶(一种新的取代联吡啶配体(6,6'-(2,4,6-三异丙基苯基)-2,2'-联吡啶))的合成以及基于该化合物的第一配位化合物的合成,结构和磁性描述了该配体。通过2,4,6-三异丙基苯基硼酸和6,6'-二溴-2,2'-联吡啶的Suzuki偶联合成三联吡啶。这里报道的是五种第一排后过渡金属氯化物(MCl 2; M = Fe,Co,Ni,Cu,Zn)的三联体配合物。四个配合物MCl 2三联体(M = Fe,Co,Ni,Zn)在空间群P 2 1 / c中结晶,并且同一个结晶溶剂分子同构。复合CuCl 2三联双在两个结晶的溶剂分子中在空间群P 2 1 2 1 2 1 1中结晶。所有的MCl 2三联体配合物都是四个配位,并且包含扭曲的四面体金属中心。CuCl 2三联体显示出伪的Jahn-Teller畸变,甲苯玻璃中的X波段电子顺磁共振(EPR)给出的g⊥,∥值约为2.2和2.1。磁测量(M =
