Abstract top

The title compound, [Cu2(NO3)2(C10H8N2)(C12H8N2)2(H2O)2](NO3)2, comprises a binuclear copper complex cation and two nitrate anions. In the doubly-charged bridged dicopper cation, each Cu atom is five-coordinated in a distorted square-pyramidal geometry, formed by one O atom of the coordinated water molecule, one O atom of a coordinated nitrate anion, two N atoms from the bidentate 1,10-phenanthroline (phen) ligand and another N atom from the 4,4'-bipyridine (bipy) ligand. The bipy ligand bridges the Cu atoms to give a centrosymmetric binuclear structure. The complex is stabilized by hydrogen bonds and aromatic ring-stacking interactions [average interplanar distance 3.3139 (2) Å and ring-centroid separation 3.7971 (9) Å.

Comment top

In the previous literatures, binuclear copper complexes containing (phen-Cu-bipy-Cu-phen) subunit (Blake et al., 1998; Wu et al., 2002; Lin et al., 2005) have been reported. In our paper, we describe another new compound containing (phen-Cu-bipy-Cu-phen) subunit, (I), (Fig.1).

Compound (I) is comprised of a binuclear copper complex cation and two nitrate anions. In the doubly charged bridged dicopper cation, each Cu center has distorted square-pyramidal geometry, formed by one O atom of the coordinated water molecule, one O atom of coordinated nitrate anion, two N atoms from bidentate 1,10-phenanthroline (phen) ligand and another N atom from 4,4'-bipyridine (bipy) (Table 1). The plane N1/N2/O1/N3 defines the base of the pyramid while water O7 occupies the apex. The distance from Cu1 to the least-squares plane N1/N2/O1/N3 is 0.1924 (4)Å towards O7. The bipy ligand bridge the Cu atoms to give this binuclear structure.

The water molecules and coordinated nitrate O atoms take part in intermolecular hydrogen bonds interactions and they join complex cations into a one-dimensional chain structure along a axis (Fig. 2 and Table 2). The chains are further expanded into two-dimensional network via the π-π stacking between 1,10-phenanthroline rings of adjacent chains of (I) (Fig. 3). The dihedral angle of aromatics involved in stacking is 0.0002 (3)°. Interplanar average distance and ring-centroid separation distance are 3.3139 (2) Å, 3.7971 (9) Å, respectively.

Experimental top

A 10 ml water solution of Cu(NO)3·3H2O (0.242 g,1 mmol) was dropped into 10 ml me thanol solution of 4,4'-bipyridine (0.078 g, 0.5 mmol) and 1,10-phenanthroline (0.18 g,1 mmol) to be stirred for 4 h at 333 K. The filtrate stayed in air for about one week to obtain blue block-shaped crystals. Analysis, found (%): C 43.85, H 3.05, N 15.16. C34H28Cu2N10O14 requires (%): C 43.98, H 3.02, N 15.09.

Refinement top

H atoms were positioned geometrically with C—H = 0.93 Å, O—H = 0.82 Å, and treated as riding atoms, with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(O).

Special details top

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.
