(Received 6 August 2010; accepted 17 August 2010; online 21 August 2010)

In the title compound, [Cu(ClO4)2(C12H8N2)(H2O)2], the CuII atom is coordinated in a square-planar fashion by the two N atoms of a chelating 1,10-phenanthroline ligand and by two water mol­ecules trans to the N atoms. The coordination sphere of the metal atom is augmented by O atoms of two weakly bonded perchlorate anions, thus yielding a strongly distorted CuN2O4 octa­hedral environment. The crystal packing is stabilized by O—H⋯O hydrogen bonds between the water mol­ecules and the perchlorate anions. In addition, the organic mol­ecules are associated by ππ stacking inter­actions between symmetry-equivalent anti­parallel non-nitro­gen aromatic rings, with inter­planar distances of 3.543 (2) Å.

Comment top

In recent years, there has been an active and concerted attention in developing metal-organic coordination materials owing to their potentially useful magnetic, electric, photochemical and catalytic properties (Kubo, 1976; Kobel & Hanack, 1986; Pierpont & Jung, 1994; Huskins & Robson, 1990). Here, the title compound, [Cu(H2O)2(C12H8N2)](ClO4)2, is presented, which has been obtained in continuation of our studies of new coordination compounds (Kaabi, et al., 2010).

In the atomic arrangement of the title material, the Cu ion is surrounded by one 1,10-phenanthroline ligand, two ClO4- anions and two water molecules. The CuII atom is coordinated in a square-planar fashion by two nitrogen atoms of a chelating o-phenanthroline ligand and two water molecules trans to the nitrogen atoms with Cu—N1 and Cu—N2 distances of 1.9953 (12) and 1.9764 (12) Å, and Cu—O1 and Cu—O2 distances of 1.9784 (10) and 1.9600 (11) Å, respectively. The coordination sphere around the metal is augmented by oxygen atoms of two weakly bound perchlorate anions, thus yielding a strongly distorted octahedral environment for the copper(II) ion (Fig. 1). The two Cu—O distances to the perchlorate anions, 2.3805 (11) and 2.5508 (11) Å, are much longer than the Cu—O(water) distances (Table 1), and especially the longer of these two distances should be regarded as a very weak interaction rather than an actual metal-oxygen bond.

The complexes are interconnected by a set of O—H···O hydrogen bonds between the water molecules and the perchlorate anions (Table 2), leading to the formation of a three dimensional network (Fig. 2). As expected, the ClO4- anion has a characteristic tetrahedral geometry where the Cl—O bond lengths and O—Cl—O angles are slightly different from one another and vary with the coordination of the individual O atoms, such as hydrogen bonds or metal coordination. In the title compound, the Cl—O bond lengths vary between 1.4272 (13) and 1.4728 (11) Å and 1.4230 (14) and 1.4490 (11) Å for the two ClO4- anions. The O—Cl—O angles range from 107.95 (7) to 111.67 (10)° for the first anion and from 108.62 (7) to 110.48 (11)° for the second anion.

Intermolecular ππ stacking interactions between neighboring non-nitrogen aromatic rings of 1,10-phenanthroline are also observed, with a face-to-face distance of 3.543 (2) Å (Fig. 3), less than 3.8 Å, the maximum value regarded as relevant for ππ interactions (Janiak, 2000).

Experimental top

An aqueous solution of Cu(ClO4)2 (1 mmol, 0.263 g) was added dropwise to a solution of 1,10-phenanthroline (1 mmol, 0.180 g) in ethanol. The resultant mixture was evaporated at room temperature. Crystals of the title compound, which remained stable under normal conditions of temperature and humidity, were isolated after several days and subjected to X-ray diffraction analysis (yield 63%).

Refinement top

C—H hydrogen atoms were placed in calculated positions with C—H distances in the range 0.93–0.97 Å. The water hydrogen atom postitions were refined with O—H distance restraints of 0.84 (2) Å. The Uiso(H) values of all H atoms were constrained to 1.2 or 1.5× Ueq of the respective parent atom.

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.
