摘　　要：The complex[Cu(L-met)(phen)(H 2 O)]NO 3 ·H 2 O has been synthesized and investigated by elemental analysis,molar conductivity,spec troscopic and X-ray diffraction methods,where phen =1,10-phenanthroline and L-met =L-methioninate group.The complex crystallized in the monoclinic space g roup P2 1 with a=12.053(2)*!,b=6.886(1)*!,c=13.385(3)*!,β=113.59(3)°,V=1018.1(3)*! 3 ,Z =2,D c =1.598g·cm -3 ,μ=1.223mm -1 ,F(000)=506,R 1 =0.0306,and w R 2 =0.0742.The copper*"atom is ligated in a distorted square-pyramidal geometry by two ni trogen atoms of one phen and the amino nitrogen atom ,one carboxylate oxygen atom of L-met in the base plane,and an aqua at t he apical position.A one-dimension al chain configuration formed by the hydrogen-bonding and weak Cu-O(the uncoordinated carboxyl oxygen a tom)coordination interactions be-tween neighboring[Cu(L-met)(phen)(H 2 O)] + cations.CCDC:183368.The complex[Cu(L-met)(phen)(H 2 O)]NO 3 ·H 2 O has been synthesized and investigated by elemental analysis,molar conductivity,spec troscopic and X-ray diffraction methods,where phen =1,10-phenanthroline and L-met =L-methioninate group.The complex crystallized in the monoclinic space g roup P2 1 with a=12.053(2)*!,b=6.886(1)*!,c=13.385(3)*!,β=113.59(3)°,V=1018.1(3)*! 3 ,Z =2,D c =1.598g·cm -3 ,μ=1.223mm -1 ,F(000)=506,R 1 =0.0306,and w R 2 =0.0742.The copper*'atom is ligated in a distorted square-pyramidal geometry by two ni trogen atoms of one phen and the amino nitrogen atom ,one carboxylate oxygen atom of L-met in the base plane,and an aqua at t he apical position.A one-dimension al chain configuration formed by the hydrogen-bonding and weak Cu-O(the uncoordinated carboxyl oxygen a tom)coordination interactions be-tween neighboring[Cu(L-met)(phen)(H 2 O)] + cations.CCDC:183368.
