摘要
羧酸配合物在磁学、光学、催化、生物等诸多领域有广泛的应用前景。羧酸配合物晶体材料的设计、合成、结构及性能的研究一直是人们研究的热点。近年来,我们用刚性芳香羧酸构筑了一些羧酸配合物㈣.但对于柔性芳香羧酸配体体系我们研究不多州。柔性芳香羧酸配体含有脂肪链具有柔性特征。同时其结构中含有芳环有助于形成π-π堆积、氢键等分子间弱相互作用,
A cadmium(Ⅱ) complex Cd2(2,4-DAA)4(phen)2 with 2,4-dichlorophenoxy acetic acid (2,4-DAA), 1,10- phenanthro line(phen) has been synthesized by means of solvothermal way and characterized. Crystal data for this complex: triclinic, space group P1, a=0.916 90(9) nm, b=1.064 51(11) nm, c=1.566 4(2) nm, α=108.482(2)°, β= 103.353(2)°, γ=96.577 0(10)°, V=1.381 4(3) nm^3, Do=1.761 g·cm^-3, Z=1, F(000)=728, Final GooF=l.020, RI= 0.026 3, wR2=0.054 1. The crystal structure shows that two neighboring cadmium(Ⅱ) ions are linked together by two bridging 2,4-dichlorophenoxy acetic acid radicals, forming a binuelear structure. Each cadmium(Ⅱ) ion is coordinated with two nitrogen atoms of one 1,10-phenanthroline molecule and four oxygen atoms from three 2,4- diehlorophenoxy acetic acid radicals, forming a distorted octahedral coordination geometry. The cyclic vohammetrie behavior of the complex was also investigated. CCDC: 727586.
