Its structure has been determined by single crystal X ray diffraction. It crystallizes in the triclinic space group P1 , with a =1.196 3(2) nm, b =1.536 5(3) nm, c =1.591 4(3) nm, α=93.97(3)°, β=110.88(3)°, γ=101.07(3)°, V =2.651 8(9) nm 3 and Z =1. Least squares refinement of the structure leads to R and R w factors of 0.067 3 and 0.162 8, respectively. An unusual structural feature of the compound is that the polyanion [Cu 4(H 2O) 2(AsW 9O 34 ) 2] 10- is linked with the amino acid complex of Cu 2+ by a μ oxygen atom.展开更多

Thiscrystal is orthorhombic, belonging to space group PC21/B with α=1. 002 1 (2) nm, b=1. 483 0(3) nm, c=2. 173 6(4) nm, V=3. 230 39(2) nm3, Z=2, Dc=1.80 g/cm3, R=0. 069 3. The structure was solved by direct method. The tin atom of the title compoundexists in two distorted-trigonal-bipyramidal geometry, defined by two carbon, one bromide,one chloride and one oxygen atoms leading to a five-membered chelate ring. In the structure,the five-membered ring containing the intermolecular O→Sn has a half chair conformation.展开更多
