Recently, we reported the synthesis and crystal structure of [(H₂DA18C6)Cl₂], (II), (Yousefi et al., 2007) [where H₂DA18C6 is 1,10 –Diazonia-18-crown-6]. Several proton transfer systems using 1,10-diaza-18 -crown-6, with proton donor molecules,such as [(H₂DA18C6)I₂·2H₂O], (III), (Chekhlov, 2005), [(H₂DA18C6)(C₂HO₄)₂], (IV), and [(H₂DA18C6)₂(C₂O₄)₂·2H₂O], (V), (Chekhlov, 2000), [(H₂DA18C6)(picrate)₂], (VI), (Chekhlov, 2001), [(H₂DA18C6)(HPTD)₂], (VII), (Simonov et al., 2003), [(H₂DA18C6)(PD)₂·(H₂O)₄], (VIII), and [(H₂DA18C6)(PS)₂·(H₂O)₂], (IX), (Fonari et al., 2004), [(H₂DA18C6)(CCl₃COO)₂(CCl₃COOH)₂], (X), (Chekhlov et al., 1994), [(H₂DA18C6)(CCl₃COO)₂], (XI), (Chekhlov & Martynov, 1998), and {[H₂DA18C6][(ArSO₂)₂N]₂}, (XII), (Moers et al., 2000) [where H₂DA18C6 is 1,10-Diazonia-18-crown-6, C₂O₄ is oxalate, HPTD is (4Z,5E)-pyrimidine-2,4,5,6(1H,3H)-tetraone 4,5-dioxime anion, PD is 2-(2-methylphenyl)-2H-[1,2,3]triazolo[4,5-d] pyrimidine-5,7(4H,6H)-dione 3-oxide anion, PS is 6-amino-2,4-dioxo-1,2,3,4-tetrahydropyrimidin-5-yl- sulfamate and (ArSO₂)₂N is bis(4-chlorobenzenesulfonyl)imide] have been synthesized and characterized by single-crystal X-ray diffraction methods.

There are also several proton transfer systems using H₂[PtCl₆] with proton acceptor molecules, such as [HpyBr-3]₂[PtCl₆]·2H₂O, (XIII), and [HpyI-3]₂[PtCl₆]·2H₂O, (XIV), (Zordan & Brammer, 2004), [BMIM]₂[PtCl₆], (XV), and [EMIM]₂[PtCl₆], (XVI), (Hasan et al., 2001), {(DABCO)H₂[PtCl₆]}, (XVI), (Juan et al., 1998), {p-C₆H₄ (CH₂ImMe)₂[PtCl₆]}, (XVIII), (Li & Liu, 2003), [het][PtCl₆]·2H₂O, (XIX), (Hu et al., 2003), [9-MeGuaH]₂[PtCl₆]·2H₂O, (XX), (Terzis & Mentzafos, 1983) and [H₁₀[30]aneN₁₀][PtCl₆]₂Cl₆·2H₂O, (XXI), (Bencini et al., 1992) [Where BMIM⁺ is 1-n-butyl-3-methylimidazolium, EMIM⁺ is 1-ethyl-3-methyl- imidazolium, DABCO is 1,4-diazabicyclooctane, het is 2-(?-hydroxyethyl) thiamine and 9-MeGuaH is 9-methylguaninium] have been synthesized and characterized by single-crystal X-ray diffraction methods. We report herein the synthesis and crystal structure of the title compound, (I).

The asymmetric unit of (I), (Fig. 1), contains one half-cation, one half-anion and one water molecule. The Pt ion has an octahedral coordination. The bond lengths and angles, in cation, are in good agreement with the corresponding values in (II) and (III). Also, the Pt—Cl bond lengths and angles (Table 1) are within normal ranges, as in [H₁₀[30]ane][PtCl₆]₂Cl₆·2H₂O, (XXII), (Bencini et al., 1992).

In the crystal structure, the intermolecular O—H···Cl, N—H···O and O—H···O hydrogen bonds (Table 2) seem to be effective in the stabilization of the crystal structure, resulting in the formation of a supramolecular structure (Fig. 2).

Experimental top

For the preparation of the title compound, (I), a solution of 1,10-diaza-18 -crown-6 (0.10 g, 0.37 mmol) in water (50 ml) was added to a solution of H₂PtCl₆·2H₂O (0.20 g, 0.37 mmol) in water (30 ml) and the resulting yellow solution was stirred for 30 min at 333 K. Then, it was left to evaporate slowly at room temperature. After 24 h, yellow prismatic crystals of (I) were isolated (yield; 0.22 g, 84%, m.p. 470–472 K).

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.
