The 4H6N3O)2[InCl5(H2O)], comprises two independent cytosinium cations and an aquapentachloridoindate anion. The InIII ion is in a slightly distorted octahedral coordination geometry. In the crystal, alternating layers of cations and anions are arranged along [010] and are linked via intermolecular N—H⋯O, O—H⋯Cl and N—H⋯Cl hydrogen bonds, forming sheets parallel to (001). Additional stabilization within these sheeets is provided by weak intermolecular C—H⋯O interactions.

A solution of 1 mmol InCl3 and 2 mmol cytosine in hydrochloric acid was slowly evaporated to dryness over a period of two weeks yielding red crystals suitable for X-ray diffraction.
All H atoms were visible in differnce Fourier maps but were introduced in calculated positions and treated as riding on C and N atoms with C—H = 0.93Å and N—H = 0.86Å and Uiso(H) = 1.2(C,N). The water H atoms were located in a difference Fourier map and their positions were refined with Uiso(H) =1.5 Ueq(O).

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. 4 bad reflections were omitted from the refinement |

The title compound, was prepared as part of our ongoing studies of hydrogen-bonding interaction in the crystal structures of protonated amines (Bouacida, 2008; Bouacida et al., 2009). The asymmetric unit of the title compound (I) is shown in Fig. 1. The bond distances (Allen et al. 1987) and angles are within the ranges of accepted values. In the title compound the imine N atom is protonated as in other related structures (Bouacida et al., 2005; Casellato, et al. 1995; Cherouana et al., 2003). The In atom is six-coordinated (by five chlorine atoms and one water molecule) forming a slightly-distorted octahedral geometry. In the crystal structure alternating layers of cations and anions are arranged along [010] and are linked via intermolecular N—H···O, O—H···Cl and N—H···Cl hydrogen bonds to form a two-dimensional sheets parallel to (001) (see Fig. 2). Additional stabilization within these sheeets is provided by weak intermolecular C—H···O interactions.
