(Received 26 August 2009; accepted 21 September 2009; online 26 September 2009)

In the title complex, [CdCl2(C18H20N2O2)], the CdII ion is coordinated by two N atoms from a bis-chelating 2,9-diprop­oxy-1,10-phenanthroline ligand and two Cl atoms in a distorted tetra­hedral environment. The two Cd—Cl bond distances are significantly different from each other and the N—Cd—N bond angle is acute. In the crystal structure, there are ππ stacking inter­actions between symmetry-related phenanthroline ring systems, with a centroid–centroid distance of 3.585 (3) Å.

Comment top

The compound 1,10-phenanthroline and its derivatives have been used with d10 metals to synthesize some luminescent materials (Arpi, et al., 2006; Bie, et al., 2006). The compound 2,9-diethoxy-1,10-phenanthroline has been shown to possesses antimycoplasmal activity in the presence of copper (Pijper, et al., 1984). Herein, we present the crystal structure of the title compound.

The molecular structure of the title compound is shown in Fig.1. The CdII ion is four-coordinated to two nitrogen atoms from one 1,10-phenanthroline ring (N1, N2) and two chlorine atoms (Cl1, Cl2), defining a distorted tetrahedral coordination geometry. The two Cd—Cl bond distances are significantly different from each other. The the N—Zn—N bond angle is acute. In the crystal structure, there are ππ stacking interactions between phenanthroline ring systems with centroid to centroid distances of 3.5847 (1) Å (Fig. 2).

Experimental top

2,9-Dipropoxy-1,10-phenanthroline was prepared according to the literature procedure (Pijper, et al., 1984). Slow evaporation of a mixture of the ligand (0.027 g, 0.1 mmol) and cadmium dichloride (0.016 g, 0.1 mmol) in 30 ml methanol afforded suitable colourless block crystals in about 7 days (yield about 45%).

Refinement top

C-bound H atoms were placed in calculated positions and refined using a riding model [C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C) for aromatic H atoms, C—H = 0.97 Å and Uiso(H) = 1.2Ueq(C) for methylene H atoms and C—H = 0.96 Å and Uiso(H) = 1.5Ueq(C) for methyl H atoms]. The final difference Fourier map had a highest peak 0.94 Å from atom C17 and a deepest hole at 0.85 Å from atom H18, but were otherwise featureless.

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.
