Crystal structure of copper(II)complex with a new aminocarboxylateligand.3-hydroxyl-1,5-diazacycloheptane-N,N'-diacetate,C,H4CuN2O,·H2O,M,=311.78 is reported.It crystallizes in orthorhombic Pna2i with a=13.34... Crystal structure of copper(II)complex with a new aminocarboxylateligand.3-hydroxyl-1,5-diazacycloheptane-N,N'-diacetate,C,H4CuN2O,·H2O,M,=311.78 is reported.It crystallizes in orthorhombic Pna2i with a=13.340(4),6=8.127(1),c=10.583(4)A,V=1147.2(7)A3,Z=4,D.=1.805g/cm3,μ=19.287em-1(MoKa),F(000)=644.The final R and Rgare 0.049 and 0.065 for 888observed reflections with 123o(1).The result of X-ray structure determination showsthat the Cu(I)forms a planar complex with two oxygen atoms and two nitrogenatoms of the ligand. 展开更多
