以3,3’,4,4’-偶氮苯四羧酸(ABTC)和1,10-菲罗啉(Phen)为配体,采用常规溶剂挥发法合成了新颖单桥配合物[Co2(ABTC)(Phen)2(H2O)6]·2H2O(1),经过X-射线单晶衍射和元素分析对其晶体结构进行表征.1属单斜晶系,空间群C12/c1(15),其晶胞参数:a=2.189 3(7)nm,b=0.801 3(3)nm,c=2.603 8(8)nm;α=90.00(°),β=108.369(5)(°),γ=90.00(°);V=4.335 06(762)nm3,Z=22,Dc=1.036 21g/cm3,F(000)=140 1,GOF=1.052,R1=0.097 6,WR2=0.128 8.1中的Co(Ⅱ)与ABTC中的一个羧基氧原子、三个水氧原子、啡啰啉的两个氮原子配位形成了六配位的八面体几何构型桥连配合物.通过两个游离的水分子和配位水分子之间的氢键作用,堆积成了三维超分子结构.
A novel monobasic coordination complex [Co2 (superscript 2 +)] was synthesized by the conventional solvent evaporation method using 3,3 ’, 4,4’-azobenzenetetracarboxylic acid (ABTC) and 1,10-phenanthroline Its crystal structure was characterized by X-ray single crystal diffraction and elemental analysis. 1 belongs to monoclinic system with space group C12 / c1 (15), The cell parameters are: a = 2.189 3 (7) nm, b = 0.801 3 (3) nm, c = 2.603 8 (8) nm; = 90.00 (°); V = 4.335 06 762 nm3 Z = 22 Dc = 1.036 21 g / cm3 F 000 = 140 1 GOF = 1.052 R1 = 0.097 6 WR2 = 0.128 Co (Ⅱ) coordinated with two nitrogen atoms of one carboxyl oxygen atom, three water oxygen atoms and phenanthroline in ABTC to form hexacoordinated octahedral geometry bridging complexes. Two free water Hydrogen bonding between molecules and coordination water molecules, stacked into a three-dimensional supramolecular structure.
