The ligand L was prepared according to reported method (Valdes-Martinez et al. 2002). The title compound was prepared by refluxing an 30 ml EtOH–HCl mixture solution (v:v = 3:1) containing an equimolar amount of L (1.096 g, 4 mmol) and CdCl2 for 1 h. The resulting solution was filtered and stood still until crystals formed.
All H atoms attached to C atoms and N atom were fixed geometrically and treated as riding with C—H = 0.96 Å (methyl) or 0.93 Å (aromatic) and N—H = 0.86 Å with Uiso(H) = 1.2Ueq(Caromatic or N) and Uiso(H) = 1.5Ueq(Cmethyl). H atoms of water molecule were located in difference Fourier maps and included in the subsequent
using restraints (O-H= 0.85 (1)Å and H···H= 1.39 (2)Å) with Uiso(H) = 1.5Ueq(O). In the last stage of structure they were treated as riding on their parent O atom.Data collection: CrystalClear (Rigaku, 2005); cell

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 asymmetric unit of the title compound (Fig 1) consists of pentachlorocadmium, a water molecule and H3L, the latter resulting from protonation of the pyridyl nitrogen and the two guanyl N atoms. There are four intramolecular hydrogen bonds in the compound, i.e., N4—H4···Cl5, N5—H5A···Cl1, N8—H8B···O1W and O1W—H1WB···Cl4 (table 1). The angle between the pyridine ring and the aminoguanidone moieties, N2—N3—C11—N4—N5 and N6—N7—C10—N8—N9, are 26.23 (2)° and 31.13 (1)° respectively. Additionally, there are also numerous hydrogen bonds among the terminal nitrogen atoms of the trication H3L, the oxygen atom of the water molecule and the chloride atoms of pentachlorocadmium anion, leading to a complex three-dimensional network.
