| 摘要: 合成了铜(Ⅱ)的手性单核配合物[Cu(OPSer)(phen)(H2O)]·3H2O(1)(H2OPSer=L-O-磷酸丝氨酸;phen=1,10-邻菲啰啉)。通过元素分析、红外光谱、热重分析和磁性对配合物进行表征,并利用单晶X-射线衍射法测定其结构。铜(Ⅱ)具有变形四方锥的配位环境,分别与1个L-O-磷酸丝氨酸离子的1个氮原子和氧原子、1个1,10-邻菲啰啉分子的2个氮原子以及1个配位水分子的氧原子配位。配合物每个分子单元通过氢键连接成三维超分子结构,分子间存在π-π堆积作用。在1.8～300K范围内磁性测定表明:配合物1中存在铁磁耦合相互作用,经理论拟合:g=2.07,zJ'=0.044。 |

| Abstract: Reaction of L-O-Phosphoserine (H2OPSer) and 1,10-phenanthroline (phen) and Cu(CH3COO)2·H2Oin water-ethanol at ambient temperature afforded the remarkably copper complex [Cu(OPSer)(phen)(H2O)]·3H2O(1). The structure has been determined by single-crystal X-ray diffraction analysis and further characterized by infrared spectra (IR), elemental analysis, thermal analysis and magnetic measurements. The chiral copper(Ⅱ) mononuclear complex self-assembled via intermolecular hydrogen bonding interactions into 3Dsupramolecular network and was further consolidated by the π-π stacking interactions. The magnetic susceptibilities (1.8～300 K) indicated that the monnuclear(Ⅱ) cores were ferromanetic coupling (g=2.07,zJ'=0.044). CCDC: 760116. |
