✦ Synopsis

The title compound, (C 27 H 26 P 3 )[AlCl 4 ]ÁCH 2 Cl 2 , was isolated from a mixture containing the triphosphenium ion and its protonated derivative. The central cation ring is non-planar, as in the analogous hexachlorostannate (though the structures are not isomorphous), and the PÐP distances are intermediate between those typical for single and double bonds.

O-tetratin(IV) , [[(CH 3 ) 2 -SnO 2 CCHCl 2 ] 2 O] 2 , two Sn atoms are six-coordinate in a C 2 SnO 4 skew-trapezoidal bipyramidal geometry [CÐSnÐC 145.7 (4) ]. The other two Sn atoms are ®ve-coordinate [CÐ SnÐC 154.3 (4) ], but the geometry is better regarded as a trans-C 2 SnO 4 octahedron owing
