Synthesis and Crystal Structure of Monoaquabenzoato-2,5,8-triaza-1, 9-di(2-fluorozenzyl)Nonane Copper(II),Benzoate, Dihydrate and Bis{dinitrato-2,5,8-triaza-1,9-di(2-fluorozenzyl)nonanecopper(II)} Monohydrate

The title compound (1), Cu(C 18 H 23 F 2N 3)(C 7H 5O 2)(H 2O)] (C 7H 5O 2)·2(H 2O), is a discrete mononuclear copper(II) complex. The Cu(II) atom is in a square pyramidal geometry and is coordinated by three N atoms from an amine ligand, two O atoms from a benzoate ligand and a water molecule, respectively. The crystal structure is composed of molecular columns which are stabilized by hydrogen bonds. The title compound (2), Cu(C 18 H 23 F 2N 3)(NO 3) 2]·12(H 2O), consists of two similar mononuclear copper(II) complexes and one lattice water molecule. The Cu(II) atom is in a square pyramidal geometry and is coordinated by three N atoms from an amine ligand, two O atoms from a benzoate ligand and a water molecule, respectively. All the nitrogen atoms in the amine ligands contribute to the formation of the hydrogen bonds. A great number of hydrogen bonds link the complexes into a three-dimensional network.
