In the crystal structure of the title compound, [Cu(NO3)(C2H4NO)(C12H8N2)]n, the CuII atoms are linked by acetamid­ate ligands, forming a chain. Each CuII atom is five-coordinated by two N atoms of the 1,10-phenanthroline ligand, one nitrate O atom, and one N and one O atoms of acetamidate in a trigonal-bipyramidal geometry. In the crystal structure, the chains are linked by hydrogen bonds into a polymeric ribbon structure.

Comment top

The crystal structure of catena-Poly[[(nitrato-κO) (1,10-phenanthroline-κ2N,N')nickel(II)]-µ-acetamido-κ2O:N], (II), has previously been reported (Liu & Zhu, 2007). The crystal structure determination of the title compound, (I), has been carried out in order to elucidate the molecular conformation and to compare it with that of (II). We report herein the crystal structure of (I).

In the molecule of (I) (Fig. 1), the ligand bond lengths and angles are within normal ranges (Allen et al., 1987). The title compound, [Cu(NO3)(C2H4NO)(C12H8N2)]n, which are linked by acetamidate ligands to form a chain. Each CuII atom is five-coordinated by two N atoms of 1,10-phenanthroline (phen) ligand, one nitrate O atom, and one N and one O atoms of acetamidate within a bipyramidal coordination geometry (Table 1). The Cu—O and Cu—N bond are in the range [1.942 (2)–2.322 (2) Å] and [1.981 (2)–2.011 (3) Å], respectively (Table 1), as in (II).

In the crystal structure, no classic C—H···O hydrogen bonds (Fig. 2 and Table 2) seem to be effective in the stabilization of the structure, resulting in the formation of a polymeric ribbon structure, as in (II).

The both compounds, (I) and (II), are isostructural.

Experimental top

Crystals of the title compound were synthesized using hydrothermal method in a 23 ml Teflon-lined Parr bomb, which was then sealed. Copper (II) nitrate hexahydrate (296.3 mg, 1 mmol), phen (180.2 mg, 1 mmol), acetamide (59.1 mg, 1 mmol) and distilled water (8 g) were placed into the bomb and sealed. The bomb was then heated under autogenous pressure up to 453 K over the course of 7 d and allowed to cool at room temperature for 24 h. Upon opening the bomb, a clear colorless solution was decanted from small blue crystals. These crystals were washed with distilled water followed by ethanol, and allowed to air-dry at room temperature.

Refinement top

The H atoms were positioned geometrically, with N—H = 0.86 Å (for NH), C—H = 0.93 and 0.96 Å for aromatic and methyl H atoms, and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C,N), where x = 1.2 for aromatic and NH H atoms and x = 1.5 for methyl H atoms.

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.
