SYNTHESES AND STRUCTURES OF NA-2[ZN-II(ID A)(2)].7H(2)O AND NA-4[HG-II(NTA)(2)].7H(2)O

The title complexes were synthesized and the crystal structures of the ir salts were determined by single-crystal X-ray structure analyses. N a-2[Zn-I(ida)(2)]. 7H(2)O: Triclinic, P1, a=0.523 4(2) nm, b=0.897 10( 10) nm, c=1.069 10(10) nm, alpha=85.910(10)degrees, beta= 76.380(10)de grees, gamma=83.52(2)degrees, V=0.484 2(2) nm(3), Z=1. The complex ani on [Zn-I (ida)(2)](2-) has a pseudo-octahedral structure in which the two N atoms: are in a trans configuration. Na-4[Hg-I(nta)(2)]. 7H(2)O: Monoclinic, C-c, a = 1.795 0(4) nm, b = 0.892 9(2)nm, c = 1.575 4(2) nm, beta = 92.78 (3)degrees, V = 2.526 2(9) nm(3), Z = 4. The complex anion [Hg-I (nta)(2)](4-) has a pseudo-bicapped-octahedral structure i n which the two N atoms are in a trans configuration.
