The copper complex with the acid [CuL(H 2O)] was obtained in aquo solution and its crystal structure was determined by X ray diffraction with a final R 1 value of 0.024 4 and a wR 2 value of 0.066 0. The crystal is of monoclinic system with a space group P2 1/C . The unit cell parameters are as follows: a =1.218 3(2) nm, b =0.868 31(10) nm, c= 0.979 40 nm , β =96.100(10)°, V =1.032 2(2) nm 3, Z =4, D c=1.862 g/cm 3, F (000)=588, μ =2.129 mm -1 . In crystal, each copper ion is coordinated with three oxygen atoms and one nitrogen atom from H 2L and an oxygen atom from water; the coordination polyhedron around Cu 2+ is a distorted tetragonal pyramid. Cu 2+ are linked by anti anti carboxyl bridges to form endless zigzag chain, a two dimensional network is obtained through the hydrogen bonds between the adjacent chains.展开更多

Its crystal structure was determined by single crystal diffraction. The crystal crystallizes in triclinic, space group P 1, a=0 8483(1) nm, b =0 9642(2) nm, c =1 2838(2) nm, α =111 17(1)°, β = 93 52(1)°, γ =100 89(1)°, Z =2, D c=2 335 g·cm -3 . The complex appears as a zigzag 1D chain. Each gadolinium ion is coordinated by three carboxylic oxygen atoms and six oxygen atoms from H 2O. Each copper ion is chelated by NTA with its nitrogen atom and three oxygen atoms of three carboxyl groups, and coordinated by a chlorine ion. The ClO 4 - is located between the chains as a counter ion.展开更多

The crystal structure of the complex was determined by X ray diffraction method. The crystal belongs to the orthorhombic system with space group Pbca, a=8.110(1), b=13\^120(2), c=20.788(2) , V=2211.9(5) 3, Z=8, F(000)=1512, μ =5\^349 mm -1 , R =0.0182 and wR =0.0385 for 1909 observed reflections with I>2σ(I) . The Sm 3+ is nine coordinated and the coordination polyhedron is a distorted, tricapped trigonal prism. The whole structure can be characterized as a two dimensional network.展开更多
