In the title compound, (C7H11N4)2[Ni(H2O)4Cl2]Cl2·4H2O, the Ni complex occupies a special position on the twofold axis; both cation and anions, as well as the water mol­ecules, are in general positions. The multiple crystallographically independent hydrogen bonds form an infinite three-dimensional network in the crystal.

FORMU_01 There is a discrepancy between the atom counts in the _chemical_formula_sum and _chemical_formula_moiety. This is usually due to the moiety formula being in the wrong format.

Comment top

In an attempt to obtain the tetrachloronickelate(II) analogues of tetrachlorocuprate(II) aminoguanidinium compounds (Alstrum-Acevedo et al., 2001), the title compound, (I), was obtained (Fig. 1).

Both pyridyl and guanyl N atoms in (I) are protonated, thus giving rise to a dicationic species. Due to the protonation of the guanyl nitrogen, two NH2 groups are attached to the C atom of the guanidine moiety. The C—N bond distances involving the two NH2 groups, viz. C8—N4 and C8—N5, as well as the N4—C8—N5 angle (Table 1), indicate considerable π-character in the bonding. Delocalization and the intramolecular N1—H1···N2 and N5—H5A···N2 hydrogen bonds (Table 2) are responsible for the planarity of the molecule.

Experimental top

1.0 mmol of aminoguanidine bicarbonate was neutralized by the dropwise addition of concentrated H2SO4 until the evolution of CO2 ceased and then added to a solution of 1.0 mmol of 2-formylpyridine in ethanol, followed by 2–3 drops of H2SO4 to catalyze the reaction. The mixture was refluxed for 5 h and slowly evaporated at ca 308 K to give a yellow solid, m.p. 463–465 K. Compound (I) was prepared by dissolving 1 mmol of the aminoguanidone in approximately 50 ml of a 3:1 EtOH–HCl (12 N) by volume, adding an equimolar amount of NiCl2.6H2O, and subsequent heating of the reaction mixture under reflux for 1 h. The solution was then filtered and the filtrate left until crystals formed.

Refinement top

H-atom positions were located in difference Fourier maps and a riding model with fixed displacement parameters [Uij = 1.2Uij(eq) of the atom to which they are bonded] was used for subsequent refinements. H atoms attached to N and O atoms were refined with fixed bond lengths r(D—H) = 0.85 Å.

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.
