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1.8~300 K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。
The chiral mononuclear complex Cu (OPSer) (phen) (H2O)] 3H2O (1) (H2OPSer = L-O-phosphoserine; phen = 1,10-phenanthroline) was synthesized. The complexes were characterized by elemental analysis, IR, TG and magnetism and their structures were determined by single crystal X-ray diffraction. Copper (Ⅱ) has a tetragonal pyramidal coordination environment, respectively, with a LO-phosphoserine ion of a nitrogen and oxygen atoms, a 1,10-phenanthroline two nitrogen atoms and a Coordination of Oxygen Atom Coordination Water Molecule. Each molecular unit of the complex is connected to a three-dimensional supramolecular structure by hydrogen bonding, and there is π-π stacking between the molecules. Magnetic measurements in the range of 1.8-300 K showed that there was a ferromagnetic coupling interaction in complex 1, and the theoretical fit was: g = 2.07, zJ ’= 0.044.
