Aquachloridodimethylphenyltin(IV)-15-crown-5 (2/1)

Abstract top

The SnIV atom in the title compound, 2[Sn(CH3)2(C6H5)Cl(H2O)]·C10H20O5, exists in a trans-C3SnClO trigonal bipyramidal geometry in which the organo substituents occupy the equatorial sites. The coordinated water molecule forms two hydrogen bonds to the 15-crown-5 molecule, which is disordered about a center of inversion.

Comment top

Water-coordinated triorganotin salts form "outer-sphere coordination" complexes with crown ethers. In these, the water molecules interact with the crown ether through hydrogen bonds (Amini et al., 1994; Chee et al., 2003; Yap et al., 1996). The refinement of such crystal structures present special difficulties when the odd-numbered crown ether is disordered about a center of inversion. The refinement of such crystal structures has been described in detail (Ng, 2005). The mixed-organo SnIV title compound, (I), has the tin atom in a trans-C3SnClO trigonal bipyramidal geometry, Fig. 1 & Table 1, in which the electronegative substituents occupy the axial sites. The coordinated water molecule forms two hydrogen bonds to the 15-crown-5, which is disordered about a center-of-inversion; Table 2.

Experimental top

ChlorodimethylphenylSnIV was synthesized by the cleavage of dimethyldiphenyltin with hydrogen chloride in a methanol/carbon tetrachloride mixture at 283 K and was purified by distillation at 363 K/1 Torr. ChlorodimethylphenylSnIV (0.26 g, 1 mmol) and 15-crown-5 (0.22 g, 1 mmol) were dissolved in ethanol (20 ml). The co-crystal (I), m.p. 347–349 K, separated when the solvent was allowed to evaporate. 1H-NMR in CDCl3: 0.90 (CH3), 1.60 (H2O), 3.72 (CH2), 7.27–7.70 (C6H5) p.p.m. 119Sn NMR 115.7 p.p.m. 2J(119Sn–1H) = 60 Hz.

Refinement top

The 15-crown-5 lies about a center of inversion and the molecule was refined as a 15-atom species of half site-occupancy. All 1,2-related atoms were restrained to 1.45±0.01 Å and 1,3-related atoms to 2.35±0.01 Å. The displacement factors of the O atoms were restrained to be equal, as were those of the C atoms.

The carbon-bound H atoms were placed in calculated positions with C–H 0.93 to 0.97 Å, and with Uiso(H) 1.2–1.5Ueq(C), and were included in the refinement in the riding-model approximation. The water H-atoms were placed in chemically sensible positions on the basis of hydrogen bonds but were not refined [O–H 0.82 Å and Uiso(H) 1.5Ueq(O)].

The final difference Fourier map had a relatively large peak/deep hole in the vicinity of the crown ether.

Figures top
[Figure 1] Fig. 1. Molecular structure of (I); ellipsoids are drawn at the 30% probability level, and H atoms as spheres of arbitrary radius. The 15-crown-5 is disordered about a center of inversion, only one orientation is shown for reasons of clarity. Dashed lines denote the water···crown-ether hydrogen bonds. Unlabelled atoms are related by the symmetry operation -x + 2, -y + 1, -z + 2.
