Abstract top

In the molecule of the title compound, [ZnCl2(C13H9N)2], the ZnII atom is four-coordinated in a distorted tetrahedral configuration by two N atoms from two phenanthridine ligands and by two terminal Cl atoms. The dihedral angle between the planes of the phenanthridine ring systems is 69.92 (3)°. An intramolecular C-H...Cl interaction results in the formation of a planar five-membered ring, which is oriented at a dihedral angle of 8.32 (3)° with respect to the adjacent phenanthridine ring system. In the crystal structure, [pi]-[pi] contacts between the phenanthridine systems [centroid-centroid distances = 3.839 (2), 3.617 (1) and 3.682 (1) Å] may stabilize the structure. Two weak C-H...[pi] interactions are also found.

Comment top

There are several ZnII complexes, with formula, [ZnCl2(N)2], such as [ZnCl2(AMS)2], (II) (Shen et al., 2004), [ZnCl2(4-CNpy)2], (III) (Steffen & Palenik, 1977), [ZnCl2(pht)2], (IV) (Çelik et al., 2004), [ZnCl2(quin)2], (V) (Cui et al., 1998), [ZnCl2(quino)2], (VI) (Markowitz et al., 2006) and [ZnCl2(meim)2], (VII) (Musie et al., 2004) [where AMS is 3-Amino-5-methylisoxazole, 4-CNpy is 4-cyanopyridine, pht is phthalazine, quin is quinoline, quino is quinoxaline and meim is 1-methylimidazole] have been synthesized and characterized by single-crystal X-ray diffraction methods.

There are also several ZnII complexes, with formula, [ZnCl2(N—N)], such as [ZnCl2(bipy)], (VIII) (Khan & Tuck, 1984), [ZnCl2(biim)], (IX) (Gruia et al., 2007), [ZnCl2(phbipy)], (X) (Kozhevnikov et al., 2006), [ZnCl2(phen)], (XI) (Reimann et al., 1966), [ZnCl2(dmphen)], (XII) (Preston & Kennard, 1969), [ZnCl2(dpdmbip)], (XIII) (Liu et al., 2004), [ZnCl2(dm4bt)], (XIV) (Khavasi et al., 2008), [ZnCl2(5,5'-dmbpy)], (XV) (Khalighi et al., 2008) and [ZnCl2(6-mbipy)], (XVI) (Ahmadi et al., 2008) [where bipy is 2,2'-bipyridine, biim is 2,2'-biimidazole, phbipy is 5-phenyl-2,2'-bipyridine, phen is 1,10-phenanthroline, dmphen is 2,9-dimethyl-1,10-phenanthroline, dpdmbip is 4,4'-diphenyl-6,6'-dimethyl-2,2'-bipyrimidine, dm4bt is 2,2'-dimethyl-4,4'-bithiazole, 5,5'-dmbpy is 5,5'-dimethyl-2,2'-bipyridine and 6-mbipy is 6-methyl-2,2'-bipyridine] have been synthesized and characterized by single-crystal X-ray diffraction methods. We report herein the synthesis and crystal structure of the title compound, (I).

In the molecule of the title compound (Fig 1), ZnII atom is four-coordinated in a distorted tetrahedral configuration by two N atoms from two phenanthridine and two terminal Cl atoms (Table 1). The bond lengths (Allen et al., 1987) and angles are within normal ranges. Phenanthridine ring systems A (N1/C1-C13) and B (N2/C14-C26) are, of course, planar and the dihedral angle between them is A/B = 69.92 (3)°. Intramolecular C-H···Cl interaction (Table 2) results in the formation of a planar five-membered ring C (Zn1/Cl1/N1/C1/H1), which is oriented with respect to the adjacent phenanthridine ring system A at a dihedral angle of 8.32 (3)°.

In the crystal structure (Fig. 2), the π–π contacts between the phenanthridine rings, Cg2—Cg3i, Cg4—Cg6ii and Cg6—Cg6ii, [symmetry codes: (i) 1 - x, -y, -z, (ii) -x, -y, -z, where Cg2, Cg3, Cg4 and Cg6 are centroids of the rings (C2-C7), (C8-C13), (N2/C14/C15/C20/C21/C26) and (C21-C26), respectively] may stabilize the structure, with centroid-centroid distances of 3.839 (2), 3.617 (1) and 3.682 (1) Å, respectively. There also exist two weak C—H···π interactions (Table 2).

Experimental top

For the preparation of the title compound, (I), a solution of phenanthridine (0.30 g, 1.66 mmol) in methanol (15 ml) was added to a solution of ZnCl2 (0.11 g, 0.83 mmol) in acetonitrile (30 ml) and the resulting colorless solution was stirred for 30 min at 313 K, and then it was left to evaporate slowly at room temperature. After one week, colorless prismatic crystals of the title compound were isolated (yield; 0.31 g, 75.5%).

Refinement top

H atoms were positioned geometrically, with C-H = 0.93 Å for aromatic H and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C).

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.
