摘要: 合成并通过单晶衍射、元素分析、红外光谱表征了配合物[(Cu)(L)(Cl)]·0.5EtOH·1.5H₂O (1)和{[Zn(L)(NO₃)]·2CH₃CN}_n (2)的结构(HL为PMBP缩4-甲基水杨酰肼; PMBP=1-phenyl-3-methyl-4-benzoyl-5-pyrazolone)。单晶衍射结果表明,配合物1中,Cu(Ⅱ)离子与来自烯醇化脱质子配体L^-的2个O原子和1个N原子,及1个氯离子配位,采取扭曲的平面正方形配位构型。而配合物2中,Zn(Ⅱ)离子采取扭曲的三角双锥配位构型,与来自L^-的NO₂电子供体,1个单齿配位的硝酸根和相邻配体吡唑啉酮N原子配位,形成沿b轴方向的一维链状结构。在310 nm紫外光激发下,配合物2在434和459 nm处有很强的荧光发射,而配体的荧光发射峰在521 nm,强度明显弱于配合物。此外,固态配体和配合物2的荧光寿命分别为7.352 8和7.755 6 μs。

Abstract: Two complexes [(Cu)(L)(Cl)]·0.5EtOH·1.5H₂O and {[Zn(L)(NO₃)]·2CH₃CN}_n (HL is the acylhydrazone ligand derived from 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone (PMBP) and 4-methyl salicylic hydrazide) have been synthesized and characterized by single-crystal X-ray diffraction, elemental analysis and IR spectroscopy. X-ray diffraction analysis results show that the coordination geometry of the Cu(Ⅱ) ion in 1 is a distorted square planar geometry with nitrogen and two oxygen atoms provided by the enolizated ligand L^-1 and one chloride anion. However, in complex 2, the Zn(Ⅱ) ion with a distorted trigonal biyramid coordination geometry is five-coordinated, involving one nitrate anion, one NO₂ donor set of an enolizated ligand L^- and one pyrazoline nitrogen atom from another adjacent acylhydrazone ligand, thus forming one dimension chain-like framework along b axis. When excited at 310 nm, complex 2 exhibits two strong emissions at 434 and 459 nm, while the ligand shows relatively weak emission at 521 nm. In addition, luminescent decay data show that the mean lifetime τ are 7.352 8 and 7.755 6 μs for HL and complex 2, respectively. CCDC: 1058420, HL·0.5EtOH; 1058421, 1; 1058422, 2.
