Abstract

The metalation of HP(SiMe3)2 with Y[CH(SiMe3)2]3 gives the homoleptic Y[P(SiMe3)2]32 (1) which crystallizes from toluene in the monoclinic space group P21/c. The yttrium atoms are in a distorted tetrahedral environment with Y-P bond lengths of 267.7 and 284.8 pm to the terminal and bridging substituents, respectively. The metathesis reaction of [1, 3-(Me3Si)2C5H3]2YCl with KPSitBu3 yields (tetrahydrofuran-O)-1, 1', 3, 3'-tetrakis(trimethylsilyl)yttrocene-tri(tert-butyl)silylphosphanide (2). The molecular structure of 2 in solution was deduced by NMR spectroscopy and X-ray crystallography. The coupling constants 1J(Y, P) and 1J(P, H) show values of 144.0 Hz and 201.0 Hz, respectively.
