牛磺酸和邻香草醛在甲醇中于0℃反应4 h制得牛磺酸缩邻香草醛席夫碱(TMSSB);以TMSSB和邻啡罗啉(phen)为混合配体经水溶液法合成了一个新型配合物{[Co(TMSSB)(phen)2]·5H2O(1)},其结构经IR和X-射线单晶衍射表征。1属单斜晶系,空间群C2/c,晶胞参数a=16.478(5),b=20.600(7),c=22.327(7),β=95.775(5)°,V=7538(4)3,Z=8,R1=0.092 9,wR2=0.163 1。1的中心Co(Ⅱ)与两个phen分子的4个氮原子,TMSSB上一个亚氨基氮原子及一个脱质子羟基氧原子配位,形成六配位的变形八面体构型;1分子间通过氢键和π-π堆积作用形成三维结构。
Taurine and o-vanillin were reacted in methanol at 0 ℃ for 4 h to prepare taurocholic acid-Schiff base (TMSSB). TMSSB and phenanthroline were synthesized by aqueous solution A novel complex {[Co (TMSSB) (phen) 2] · 5H2O (1)} was synthesized and its structure was characterized by IR and X-ray single crystal diffraction. 1 is a monoclinic with a space group of C2 / c with unit cell parameters of a = 16.478 (5) , b = 20.600 (7) , c = 22.327 (7) and β = 95.775 (5) 7538 (4) 3, Z = 8, R1 = 0.092 9, wR2 = 0.163 The center Co (Ⅱ) of 1.1 and the four nitrogen atoms of two phen molecules, an imino nitrogen atom on TMSSB and a deprotonated Hydroxyl oxygen atoms coordinate to form hexa-coordinated distorted octahedral configuration; one molecule forms a three-dimensional structure through hydrogen bonding and π-π stacking.
