“…Another compounds which contain [FeCl 5 (H 2 O] 2-anions and organic cations such as are H 4 (cyclam) 4+ , (enH 2 ) 2+ and (dienH 3 ) 3+ have been recently prepared and characterized (Subramanian 1993, James 2001. The crystals of (NH 4 ) 2 [FeCl 5 (H 2 O)] have been usually prepared by slow evaporation of aqueous solutions containing a (1-2):1 molar mix of NH 4 Cl and FeCl 3 ·6H 2 O (Sharma 1974, Figgis 1978, McElearney 1978, Partiti 1985. This compound was also obtained from hydrochloric acid solutions (Attenborough 1997).…”

The title compound, (NH 4 ) 2 [FeCl 5 H 2 O] has been prepared by reaction between iron(III) chloride and ammonium chloride which was formed by hydrolysis of isonicotinamide or thionicotinamide in ethanol. The characterization was based on elemental analysis and infrared spectra. The crystal structure of the title compound has been refi ned by single crystal X-ray diffraction method at 293 K. Crystals are orthorhombic, Pnma, with unit cell parameters: a = 13.760(1) Å, b = 9.960(1) Å, c = 7.060(1) Å, Z = 4 and R = 3.5 %. The iron(III) atom in [FeCl 5 2-ion is approximately octahedrally coordinated by fi ve Cl atoms and one O atom of H 2 O molecule. This distortion is caused by the extensively hydrogen-bonded lattice. Structural parameters and IR spectra of similar compounds are compared and discussed.

“…In addition, the chelate complex formed is often neutral, enabling 'capture' of unstable oxidation states in metals, e.g. with tris(pyridine-2-carboxylato-N,O)manganese(III) monohydrate (Figgis, Raston, Sharma & White, 1978), and dibromo (pyridine-2-carboxylato-N,O)gold(III) (Dar et al, 1992). Also, a number of simple structures involving common transition metals and often mixed-ligand systems appear both in earlier and current literature, e.g.…”

The structure of the monohydrated polymorph of picolinic acid hydrochloride, C6H6NO~.C1-.H20, has been determined and the role of the lattice water in the hydrogen bonding to the chloride ion considered. In the anhydrous complex of the same compound, an interaction between the chloride and the pyridinium proton is found [C1... CommentPicolinic acid (pyridine-2-carboxylic acid) is of considerable interest, particularly to coordination chemists, as it possesses a potentially uninegative bidentate (N,O) donor system with the ability to stabilize complexes through the formation of six-membered chelate tings about metal centres. In addition, the chelate complex formed is often neutral, enabling 'capture' of unstable oxidation states in metals, e.g. with tris(pyridine-2-carboxylato-N,O)manganese(III) monohydrate (Figgis, Raston, Sharma & White, 1978), and dibromo (pyridine-2-carboxylato-N,O)gold(III) (Dar et al., 1992). Also, a number of simple structures involving common transition metals and often mixed-ligand systems appear both in earlier and current literature, e.g. bis (pyridine-2-carboxylato-N,O )copper(II) monohydrate (Faure, Loiseleur & Thomas-David, 1973) andThe structures of both picolinic acid (Takusagawa & Shimada, 1973) and its anhydrous hydrochloride (Laurent, 1965) have been determined. In an attempted preparation of an antimony(III) complex with picolinic acid, analogous to the trimethyl-and triphenylantimony(HI) complexes with picolinic acid (Domagala, Huber & Preut, 1990), a white crystalline solid was isolated, which was subsequently identified as a hydrated polymorph of picolinic acid hydrochloride, (I). Since this compound had not previously been reported in the literature, its structure was determined and is reported here. H•+ COOH (I).CI-.H20The planar 2-carboxypyridinium cation is conformationally similar to the anhydride (Laurent, 1965) ExperimentalThe title compound was isolated as a byproduct from the reaction mixture obtained after refluxing a 1:3 molar ratio of antimony(III) chloride and pyridine-2-carboxylic acid (picolinic acid) in water. Colourless prisms formed upon partial evaporation of the solution at room temperature. The structure was solved by direct methods using SHELXS86 (Sheldrick, 1985) and refined by full-matrix least squares (SHELXL93; Sheldrick, 1993) with anisotropic displacement parameters for all non-H atoms. H atoms were located by difference methods and included with both positional and displacement parameters refined. Other programs used wereXtal3.2 (Hall, Flack & Stewart, 1992) and PLATON (Spek, 1990).The authors acknowledge financial assistance from the Australian Research Council, the University of Queensland and the Centre for Instrumental and Developmental Chemistry of the Queensland University of Technology.Lists of structure factors, anisotropic displacement parameters and H-atom coordinates have been deposited with the IUCr (Reference: AS1154).
