COPPER(II) NITRATE COMPOUNDS WITH HETEROCYCLIC LIGANDS - STRUCTURES OF [CU(NO3)(2,2'-DIPYRIDYL)(2)][NO3]CENTER-DOT-H2O AND [CU(H2O)(1,10-PHENANTHROLINE)(2)][NO3](2)

The crystal and molecular structures of [Cu(NO3)(2,2'-dipyridyl)(2)](NO3). H2O (1) and [Cu(H2O)(1,10-phenanthroline)(2)](NO3)(2) (2) have been determined by single crystal X-ray diffraction. The copper cation in 1 displays pseudo-octahedral geometry with ligand nitrogen donors occupying four positions, a coordinated nitrate oxygen a fifth and a nonbonded oxygen a sixth. The copper cation in 2 shows a trigonal bipyramidal geometry with ligand nitrogen donors occupying the axial and two of the equatorial positions, and a coordinated aqua oxygen the other.
