Tetra-μ-chlorido-bis­(18-crown-6)platinum(II)dipotassium(I)

Abstract

In the title compound, [K2PtCl4(C12H24O6)2], the PtII ion is located on an inversion centre and is coordinated by four Cl atoms, forming a square-planar geometry. The KI ion is coordinated by six O atoms of the crown ether and two bridging Cl atoms. The KI ion is displaced by 0.756 (2) Å from the mean plane of the six O atoms of the crown ether. The mol­ecules are connected by weak C—H(...)O hydrogen bonds, forming an infinite two-dimensional network parallel to the (10An external file that holds a picture, illustration, etc.

Comment

The platinum complex, cis-diamminedichloroplatinum(II) (cisplatin), is one of the most widely used antitumour drugs in the world (Weiss & Christian, 1993; Loehrer et al., 1988). Due to the importance of the metal platinum, we report here the crystal structure of the title compound, (I).

The bond lengths and bond angles in (Fig. 1) are within normal ranges (Allen et al., 1987). The PtII ion exhibits a distorted square planar coordination geometry. The geometry is completed by four chorine atoms. The K+ ion is coordinated by six oxygen atoms of the crown ether and also by two terminal Cl atom attached to the metal platinum, forming a eight-fold coordination. The O atoms are oriented towards the centre of the crown ether cavity and O—C—C—O fragments have alternate +SC and –SC conformations. The K+ cation is displaced by 0.756 (2) Å from the mean plane of the six oxygen atoms of the crown ether.

The crystal packing is consolidated by C—H···Cl and weak C—H···O hydrogen bonds. The molecules form an infinite two dimensional network parallel to the (102) plane through the C—H···O hydrogen bonds.

Experimental

A mixture of potassium tetrachloroplatinate(II) (K2PtCl4; 0. 0208 g, 0.05 mmol) and 18-crown-6 ether (0.026 g, 0.1 mmol) in acetone and benzene (5/5 ml) was heated at 313 K with stirring for 30 min. The yellow colour solution was allowed to undergo slow evaporation. Fine orange crystals are formed after three days.

Refinement

All H atoms were positioned geometrically (C—H = 0.99 Å) and refined using a riding model, with Uiso(H) = 1.2Ueq(C). The highest peak in the difference Fourier map is located 1.07 Å from atom Pt1.

Special details

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