In the title compound, [Cu(NO3)2(C15H19N3O)], the CuII ion is coordinated by the N atoms of the tetradentate 3-[bis(2-pyridylmethyl)amino]propanol ligand and two O atoms from two monodentate nitrate anions, resulting in a distorted square-pyramidal environment. An intermolecular O—H⋯O hydrogen-bonding interaction between the free hydroxy group of the ligand and a nitrate O atom of an adjacent complex unit, gives a chain structure which extends across the (101) planes.

A MeOH solution (5 ml) of Cu(NO3)2 . 3H2O (47 mg, 0.194 mmol) was added to a MeOH solution (5 ml) of N,N-bis(2-pyridylmethyl)-3-aminopropanol (bpap, 50 mg, 0.194 mmol) (Young et al., 1995). The color changed to blue-green, and the solution was stirred for 10 min at room temperature. Blue-green crystals were obtained by diffusion of diethyl ether into the reaction mixture in methanol and were collected by filtration, washed with diethyl ether, and dried in air (yield: 36 mg, 42%). FTIR (KBr, cm-1): 3399, 1437, 3069, 2970, 2862, 1054, 1608.
All H atoms in the title compound were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H distances of 0.95 (ring H atoms) or 0.99 (open chain H atoms) Å and an O—H distance of 0.84 Å, and with Uiso(H) values of 1.2 or 1.5 times Ueq(C,O).
The preparation and characterization of a large number of polyamine complexes has been done, in order to elucidate the mechanisms of metalloenzymes (Tshuva & Lippard, 2004). Recently, the complexes with bis(2-pyridylmethyl)amine moieties have been widely described (Bebout et al.,1998; Shin et al., 2010) because the tridentate unit is a good candidate for potential biological applications (van Staveren et al., 2002). For example, palladium(II) and platinum(II) complexes with bis(2-pyridylmethyl)amine or its derivatives have been investigated as potential anticancer agents, e.g. cis-platin (Rauterkus et al., 2003). Here, we report the synthesis and
of five-coordinate Cu(NO3)2 complex with the tetradentate ligand N,N-bis(2-pyridylmethyl)-3-aminopropanol = bdap), the title compound [Cu(bpap)(NO3)2] (I), and the structure is reported here.In the title compound (Fig. 1), the CuII ion is five-coordinated and exhibits a distorted square pyramidal geometry, the equatorial plane being defined by the three nitrogen atoms of the bdap ligand and one oxygen atom of a nitrate ion. The coordination geometry is completed by the axial coordination of the oxygen atom of the second nitrate anion. The Cu—Leq bond lengths are in the range of 1.965 (4) and 2.093 (3) Å and the Cu—Oax bond length is 2.248 (3) Å. Both nitrate ions are bound in η1-fashion. The bond angles about the copper atom range from 76.95 (12) to 165.48 (15)°. The packing structure involves a strong O—H···O hydrogen bonding interaction between the free hydroxyl group of the bpap ligand and a nitrate O atom of an adjacent complex unit (Table 1), giving a one-dimensional chain structure which extends across the (101) planes in the (Fig. 2).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The preparation and characterization of a large number of polyamine complexes has been done, in order to elucidate the mechanisms of metalloenzymes (Tshuva & Lippard, 2004). Recently, the complexes with bis(2-pyridylmethyl)amine moieties have been widely described (Bebout et al.,1998; Shin et al., 2010) because the tridentate unit is a good candidate for potential biological applications (van Staveren et al., 2002). For example, palladium(II) and platinum(II) complexes with bis(2-pyridylmethyl)amine or its derivatives have been investigated as potential anticancer agents, e.g. cis-platin (Rauterkus et al., 2003). Here, we report the synthesis and crystal structure of five-coordinate Cu(NO3)2 complex with the tetradentate ligand N,N-bis(2-pyridylmethyl)-3-aminopropanol = bdap), the title compound [Cu(bpap)(NO3)2] (I), and the structure is reported here.
In the title compound (Fig. 1), the CuII ion is five-coordinated and exhibits a distorted square pyramidal geometry, the equatorial plane being defined by the three nitrogen atoms of the bdap ligand and one oxygen atom of a nitrate ion. The coordination geometry is completed by the axial coordination of the oxygen atom of the second nitrate anion. The Cu—Leq bond lengths are in the range of 1.965 (4) and 2.093 (3) Å and the Cu—Oax bond length is 2.248 (3) Å. Both nitrate ions are bound in η1-fashion. The bond angles about the copper atom range from 76.95 (12) to 165.48 (15)°. The packing structure involves a strong O—H···O hydrogen bonding interaction between the free hydroxyl group of the bpap ligand and a nitrate O atom of an adjacent complex unit (Table 1), giving a one-dimensional chain structure which extends across the (101) planes in the unit cell (Fig. 2).
