The title complex, [Cd(C2HN9)(C10H8N2)2]·0.5C10H8N2·H2O, was prepared under hydrothermal reaction conditions. The asymmetric unit contains the cadmium complex, half a 2,2'-bipyridine solvent molecule and a solvent water molecule. The CdII ion is coordinated by four N atoms from two 2,2'-bipyridine ligands and two N atoms from an HBTA- anion ligand [where H2BTA is N,N-bis(1H-tetrazol-5-yl)amine], forming an octahedral geometry. The complex is linked into a three-dimensional network by O-H
N and N-H
N hydrogen bonds and by the stacking interactions of rings, with distances of 3.5-3.7 Å between the atoms of two parallel 2,2'-bipyridine rings.
A 20 mL aqueous solution of Cd(Cl)2.4H2O (0.026 g, 0.1 mmol), H2BTA (0.016 g, 0.01 mmol) and 2,2'-bipyridine (0.039 g, 0.025 mmol) was heated in a 25 ml Teflon-lined autoclave at 433 K for 3 d, followed by slow cooling to room temperature. The resulting mixture was filtered and washed with 95% methanol, and colorless crystal were collected and dried in air. Elemental analysis, calc (%) for C27H23Cd1N14O1: C 48.21, H 3.42, N 27.08; found (%): C 47.96, H 3.87, N 26.78.
All hydrogen atoms were located in difference Fourier maps and freely refined with isotropic displacement parameters.

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. |

The H2BTA (where H2BTA is N,N-bis(1(2)H-tetrazol-5-yl)-amine) and its deprotonated anions contain nine nitrogen electron-donating atoms and show hundreds of different coordinating or bridging modes in their complexes. However, the complexes of H2BTA ligand have been not widely investigated in past decades (Friedrich et al., 2005). The title complex, (I), consists of the cadmium complex of 2,2'-bipyridine and HBTA- anion ligands, half 2,2'-bipyridine guest molecule and a solvent water molecule (Fig. 1). The HBTA- ligand acts as a chelatingbidentate and the CdII cation is coordinated to four N atoms from two 2,2'-bipyridine ligands and two N atoms from a HBTA- anion ligand to form an octahedral mononuclear complex. In the crystal structure, an extensive range of O—H···N and N—H···N hydrogen bonds as well as the stacking interactions of aryls between the parallel 2,2'-bipyridine molecules links the complex, 2,2'-bipyridine guest molecules and the water molecules into a three dimensional networks (Table 1 and Fig. 2).
