The 10H18N8S2)2[BiCl6]NO3·2H2O, contains two independent 3-amino-1-carbamothioyl-5-[(2-{[(5-methyl-1H-imidazol-3-ium-4-yl)methyl]sulfanyl}ethyl)amino]-1H-1,2,4-triazol-4-ium cations, one hexachloridobismuthate anion, one nitrate anion and two solvent water molecules. The dihedral angles between the imidazole and triazole rings in the cations are 44.7 (3) and 89.4 (3)°. The BiIII ion is coordinated by six chloride ligands in a slightly distorted octahedral geometry. In each cation, an intramolecular N—H⋯S hydrogen bond is observed. In the crystal, N—H⋯Cl, N—H⋯S, N—H⋯O, O—H⋯Cl, O—H⋯S and O—H⋯O hydrogen bonds connect the components into a three-dimensional network. In addtion, π–π stacking interactions between inversion-related triazole rings are observed, with a centroid–centroid distance of 3.322 (3) Å

Bismuth nitrate (0.4851 g, 1.0 mmol) was dissolved in 4M hydrochloric acid (30 ml). An ethanolic solution of cimetidine (0.5047 g, 2.0 mmol) and thiosemicarbazide (0.1823 g, 2.0 mmol) were added slowly to the solution with constant stirring. The solution was stirred further for 3 h and then it was filtered and left with slow evaporation of the solvent. Colorless crystals suitable for X-ray analysis separated out from the solution after a week.
H atoms bonded to C atoms were placed in calculated positions [C—H = 0.95 Å, 0.98 Å and 0.99 Å] and refined in a riding-model approximation with Uiso(H) = 1.2Ueq(C) or Uiso(H) = 1.2Ueq(Cmethyl). H atoms bonded to N and O atoms were refined independently with a common isotropic displacement parameter for each type.
The hexachlorobismuthate(III) anion, [BiCl6]3–, forms complexes with organic cations in the presence of excess chloride ions (Lazarini, 1987; Jarraya et al., 1993; Battaglia & Corradi, 1986). Cimetidine, N-cyano-N'-methyl-N"-{2-[5-methy-1H-imidazole-4-yl]methylthio-ethyl}-guanidine, consists of three main functional units: a 4,5-disubstituted imidazolic ring, a cysteine and an N-cyanoazamethine or guanidine derivative. The N-cyanoazamethine part of cimetidine reacts with thiosemicarbazide when the reaction is carried out with Bi(NO3)3 in presence of hydrochloric acid. The
of the title compound is presented herein.The molecular structure of the title compound is shown in Fig. 1. The π–π stacking interactions with Cg···Cg(1-x, 1-y, -z) = 3.322 (3)Å are observed [Cg is the centroid of the N4/C7/N6/N5/C8 ring].
compound, contains of two dicationic ligands, one [BiCl6]3– anion, one NO3- anion and two solvent water molecules. The BiIII ion is coordinated by six chloride ions forming a slightly distorted octahedral configuration with Bi—Cl bond lengths ranging from 2.6312 (13) to 2.7984 (12)Å. The Bi–Cl bond lengths are comparable with the reported values in a related halogenobismuthate (Bednarska-Bolek et al., 2000). The bond angles within the [BiCl6]3– anion of the compound do not suggest any steric interactions are present (Bednarska-Bolek et al., 2000; Jarraya et al., 1993). The dihedral angles between the imidazole and triazole rings in the cations are 44.7 (3) [C1-C3/N1/N2 and N4-N6/C7/C8] and 89.4 (3)° [C11-C13/N11/N12 and C17/C18/N14-N16]. In each cation, an intramolecular N—H···S hydrogen bond is observed. In the crystal, N—H···Cl, N—H···S, N—H···O, O—H···Cl, O—H···S and O—H···O hydrogen bonds connect the components of the structure into a three-dimensional network (Fig. 2).

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 hexachlorobismuthate(III) anion, [BiCl6]3–, forms complexes with organic cations in the presence of excess chloride ions (Lazarini, 1987; Jarraya et al., 1993; Battaglia & Corradi, 1986). Cimetidine, N-cyano-N'-methyl-N"-{2-[5-methy-1H-imidazole-4-yl]methylthio-ethyl}-guanidine, consists of three main functional units: a 4,5-disubstituted imidazolic ring, a cysteine and an N-cyanoazamethine or guanidine derivative. The N-cyanoazamethine part of cimetidine reacts with thiosemicarbazide when the reaction is carried out with Bi(NO3)3 in presence of hydrochloric acid. The crystal structure of the title compound is presented herein.
The molecular structure of the title compound is shown in Fig. 1. The asymmetric unit compound, contains of two dicationic ligands, one [BiCl6]3– anion, one NO3- anion and two solvent water molecules. The BiIII ion is coordinated by six chloride ions forming a slightly distorted octahedral configuration with Bi—Cl bond lengths ranging from 2.6312 (13) to 2.7984 (12)Å. The Bi–Cl bond lengths are comparable with the reported values in a related halogenobismuthate (Bednarska-Bolek et al., 2000). The bond angles within the [BiCl6]3– anion of the compound do not suggest any steric interactions are present (Bednarska-Bolek et al., 2000; Jarraya et al., 1993). The dihedral angles between the imidazole and triazole rings in the cations are 44.7 (3) [C1-C3/N1/N2 and N4-N6/C7/C8] and 89.4 (3)° [C11-C13/N11/N12 and C17/C18/N14-N16]. In each cation, an intramolecular N—H···S hydrogen bond is observed. In the crystal, N—H···Cl, N—H···S, N—H···O, O—H···Cl, O—H···S and O—H···O hydrogen bonds connect the components of the structure into a three-dimensional network (Fig. 2). In addtion, π–π stacking interactions with Cg···Cg(1-x, 1-y, -z) = 3.322 (3)Å are observed [Cg is the centroid of the N4/C7/N6/N5/C8 ring].
