1-Phenyltetrazole was prepared by heterocyclization of aniline with ethylorthoformate and sodium azide in acetic acid (Gaponik et al., 1985). The title compound was prepared by adding CuCl2×2H2O (0.46 g) to a heated solution (303 K) of 1-phenyltetrazole (0.73 g) in ethanol (20 ml) with stirring. The reaction mixture was heated on a water bath for 5–7 min. Single crystals were grown by slow evaporation from the reaction mixture at 289–291 K for 1 month [0.8 g, yield 32%].
H atoms were included in idealized positions (C—H = 0.93 Å) and refined using a riding model [Uiso(H)=1.2Ueq(C)]. The disordered 1-phenyltetrazole molecule was refined using an appropriate series of restraints. Details are given in the final instruction file, which is included in the supplementary material.

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. Some details of the refinement may be seen from the RES: TITL MMD2 in P-1 CELL 0.71073 7.264 11.669 12.745 95.91 104.37 92.93 ZERR 2.00 0.002 0.004 0.003 0.02 0.02 0.03 L A T T 1 SFAC C H N CL CU UNIT

This work continues our X-ray studies of transition metal complexes with bulky 1-alkyl- and 1-aryltetrazole ligands. Previously, we reported the structures of CuCl2 complexes with 1-tert-butyl- (Ivashkevich et al., 2002) and 1-(2,4,6-trimethylphenyl)tetrazole (Ivashkevich et al., 2003). The present paper is concerned with the crystal structure determination of a new complex, catena-poly[[bis(cis-1-phenyltetrazole-κN1) copper(II)]di-µ-chloro], which crystallizes as the 2:1 adduct, (I), with 1-phenyltetrazole; the asymmetric unit of (I) contains two 1-phenyltetrazole ligands (A and B) and an uncoordinated 1-phenyltetrazole molecule (C; Fig. 1).
The tetrazole rings of ligands A and B have very similar geometries, close to those previously observed for 1-substituted tetrazoles [Cambridge Structural Database (CSD); Version 5.25 of November 2003; Allen, 2002]. These rings are essentially planar, with mean deviations of tetrazole ring atoms from their least-squares planes of 0.004 (3) and 0.003 (2) Å for ligands A and B, respectively.
The interplanar angle between the phenyl and tetrazole rings is 15.23 (14)° for ligand A and 21.67 (16)° for ligand B. The N1—C6 bond lengths [1.439 (3) and 1.430 (3) Å for ligands A and B, respectively] are typical of N—Carom single bonds with cyclic pseudoaromatic nitrogen. A search of the CSD gives a mean bond length of 1.426 (18) Å for such bonds.
The bond lengths of ligands A and B are close to those of the free 1-phenyltetrazole ligand (Matsunaga et al., 1999). All of the corresponding values fall within the 3σ range. The corresponding bond angles differ slightly more, but fall within the 5σ range. The most important difference is observed in the interplanar angle between the tetrazole and phenyl rings; the value of 11.8 (1)° for the molecule in 1-phenyltetrazole crystal differs from those of ligands A and B.
The coordination polyhedron of the Cu atom is a highly elongated octahedron (Table 1). The equatorial positions are occupied by the two Cl atoms [Cu—Cl1 = 2.2687 (9) Å and Cu—Cl2 = 2.2803 (7) Å] and the two N4 atoms of the 1-phenyltetrazole ligands [Cu—N4A = 2.0131 (19) Å and Cu—N4B = 2.0317 (18) Å]. The ligands are coordinated in a cis orientation. The Cu—Cl distances for the axial Cl1i and Cl1ii atoms are 3.0307 (12) and 2.8768 (11) Å, respectively.
The coordination polyhedra of the adjacent Cu atoms share edges, forming a one-dimensional polymeric structure, [CuCl2(C7H6N4)2]n. These infinite chains extend parallel to the a axis (Fig. 2). C5B—H5B···Cl1i and C5A—H5A···Cl2ii hydrogen bonds (Steiner, 1996) are observed within the polymeric chains (Table 2).
In view of lack of classical hydrogen bonds in the structure of (I), the packing structure is determinated by weaker interactions. The infinite chains are linked into two-dimensional networks by C9A—H9A···N3Biii hydrogen bonds and by face-to-face π–π interactions between symmetry-related phenyl rings of ligands A [symmetry code: 1 − x, 1 − y, 2 − z], with an intercentroid distance of 3.704 (2) Å and offset an value of ca 1.48 Å. These two-dimensional networks, which are parallel to the xz plane, are linked by intermolecular π–π stacking interactions between symmetry-related benzene rings of ligands B [symmetry code: 2 − x, −y, 1 − z], with an intercentroid distance of 4.055 (2) Å and an offset value of ca 1.93 Å, to form a three-dimensional network (Fig. 2).
This three-dimensional network contains a potential `solvent accessible area' with a volume of ca 230 Å3 and a possible electron count of 75 per unit cell (Spek, 2003), which is consistent with the presence of one 1-phenyltetrazole molecule. Analysis of the ΔF map indeed showed that the `solvent accessible area' contained 1-phenyltetrazole molecule C. This molecule is associated with the 1 Wyckoff position, the C6C atom being displaced from the inversion center by ca 0.08 Å. As a consequence, the molecule is disordered over two positions, each with an occupancy of 0.5 (Fig. 2).
Comparison of the structure of (I) with those of previously investigated CuCl2L2 complexes, where L is 1-tert-butyl- (Ivashkevich et al., 2002) and 1-(2,4,6-trimethylphenyl)tetrazole (Ivashkevich et al., 2003), shows that all they form one-dimensional polymeric chains with a copper–chlorine skeleton. However, the polymeric chains in (I) are linked by intermolecular C—H···N and π–π interactions, forming a three-dimensional network, while the polymeric chains in the previously investigated CuCl2L2 complexes, which contain no guest molecules, are connected only by van der Waals interactions.
