catena-Poly[heptylenediammonium [[tetrachloridobismuthate(III)]-[mu]-chlorido]]

Abstract top

The title organic-inorganic hybrid compound, {(C7H20N2)[BiCl5]}n, consists of distorted corner-joined [BiCl6] octahedra forming zigzag polymeric anionic chains parallel to [001], separated by columns of heptylenediammonium cations. The asymmetric unit contains two crystallographically independent bismuth metal atoms, one of which lies on an inversion centre and the other on a twofold axis. In the crystal, the polymeric chains and cations are linked by N-H...Cl hydrogen bonds, forming undulating layers parallel to (110).

Comment top

Alkylammonium halogenoantimonates and bismuthates of general formula R2MX5, R3M2X9 and R5M2X11 (R: organic cations, M: Sb or Bi, X: Cl, Br or I) have recently attracted considerable attention since some of these compounds have revealed interesting properties (ferroelectric and non-linear optical) which make them promising materials from the viewpoint of applications (Ciapala et al., 1997; Bednarska-Bolek et al., 2000; Bator et al., 1998). The crystal lattices of the halogenometallates compounds are built of distorted MX63- octahedra which are either isolated or linked to each other by corners, edges and faces. The anionic sublattices of the halogenoantimonates and bismuthates compounds of formula R3M2X9 (Ouasri et al., 2001; Jeghnou et al., 2005; Ouasri et al., 2012; Rhandour et al., 2011) are built of distorted MX63- octahedra connected with each other, by corners, edges and faces, in such a way that three halogen atoms of the coordination sphere of Sb or Bi atoms are bridging and three are terminal. The aim of the present work was to study the recently synthesized title compound by X-ray diffraction to obtain informations about its crystal structure at ambient temperature.

The structure of the organic-inorganic hybrid title compound is built up from inorganic polymeric anions and organic cations (Fig. 1). In this structure, each bismuth cation is surrounded by six chlorine anions building a distorted BiCl63- octahedron, with Bi—Cl distances varying from 2.5520 (8) to 2.9732 (10) Å. The octahedra are corner-joined to form one-dimensional zig-zag chains propagating along the c axis. The periodic length of this string is three octahedra. In the crystal structure, the chains and organic cations are linked together by N—H···Cl hydrogen bonds(Table 1) to build undulated sheets parallel to the (1 1 0) plane (Fig. 2).

Experimental top

Single crystals of the title compound were obtained by slow evaporation, at room temperature, of an aqueous solution containing stoichiometric amounts of 1,7-diaminoheptane NH2(CH2)7NH2 (acidified with HCl in a large excess) and bismuth(III) oxide Bi2O3.

Refinement top

All H atoms were located in a difference Fourier map and treated as riding, with C—H = 0.97 Å, N—H = 0.89 Å, and with Uiso(H) = 1.2 Ueq(C, N). One outlier (1 1 1) was omitted in the last cycles of refinement.

Special details top

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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.
