利用3,5-二氨基苯甲酸配体合成了2种新的配合物[Cd(diaba)(phen)2]NO3·H2O(1)和[Zn(diaba)(2,2′-bipy)2](2)(H2diaba=3,5-diaminobenzoic acid;phen=1,10-phenanthroline,2,2′-bipy=2,2′-bipyridine),并对其进行了元素分析、红外光谱和X射线单晶衍射测定。配合物1属于正交晶系,空间群为Fddd,a=1.425 81(7)nm,b=2.564 62(13)nm,c=3.092 47(17)nm。配合物2属于单斜晶系,空间群为C2/c,a=1.273 62 nm,b=1.592 78 nm,c=1.519 35 nm,β=107.334°。配合物1和2都为单核晶体。配合物1的结构单元由1个CdII、1个3,5-二氨基苯甲酸和2个phen构成。配合物2的结构单元由1个ZnII、1个3,5-二氨基苯甲酸和2个2,2′-bipy构成。两种配合物再通过氢键或π-π堆积形成三维超分子网络。研究了配合物的热稳定性和荧光性质。
Two new complexes [Cd (diaba) (phen) 2] NO 3 · H 2 O (1) and [diazba (2,2’-bipy) 2 (2) (H2diaba = 3,5-diaminobenzoic acid; phen = 1,10-phenanthroline, 2,2’-bipy = 2,2’-bipyridine), and its elemental analysis, infrared spectroscopy and X-ray Single crystal diffraction measurement. Complex 1 belongs to the orthorhombic system with space group Fddd, a = 1.425 81 (7) nm, b = 2.564 62 (13) nm and c = 3.092 47 (17) nm. Complex 2 belongs to the monoclinic system with space group C2 / c, a = 1.273 62 nm, b = 1.592 78 nm, c = 1.519 35 nm and β = 107.334 °. Both complexes 1 and 2 are mononuclear crystals. The structural unit of complex 1 consists of one CdII, one 3,5-diaminobenzoic acid and two phen. The structural unit of complex 2 consists of one ZnII, one 3,5-diaminobenzoic acid and two 2,2’-bipy. The two complexes then form a three-dimensional supramolecular network by hydrogen bonding or π-π stacking. The thermal stability and fluorescence properties of the complexes were studied.
