✦ Synopsis

The structure of the title monomeric phosphosilicate, C 54 H 45 O 4 PSi 3 Á0.263CH 2 Cl 2 or (Ph 3 SiO) 3 POÁ0.263CH 2 Cl 2 , is reported and is the first of a phosphosiloxane molecule with the general formula (R 3 SiO) 3 PO. Although the three P V -O-Si angles are remarkably similar [143.57 (16), 144.47 (15) and 144.71 (15) ], the three P-O(Si) distances are remarkably different at 1.544 (2), 1.554 (2) and 1.561 (2) A ˚.

In the title compound, [Fe(C 5 H 5 )(C 4 H 9 NSi)(C 18 H 15 P)(CO)]-(CF 3 SO 3 )Á0.5CH 2 Cl 2 , the Fe II atom is coordinated by carbonyl, triphenylphosphine, trimethylsilyl isocyanide and cyclopentadienyl ligands in a typical piano-stool structure. The Fe-C-N-Si arrangement is almost linear and the
