ABSTRACT The reaction of the open-structure anion PW9O34((BuSiOH)-Bu-t)(3)(3-) with RSiCl3 (R = (CH2)(n)CH=CH2 (n = 0, 1, 4)) affords PW9O34((BuSiO)-Bu-t)(3)(SiR)(3-) heterosilylated capped hybrid compounds. These complexes were characterized by infrared spectroscopy and in solution by multinuclear (H-1, Si-29, P-31 and W-183) NMR. Crystals of (Bu4N)-Bu-n(3)PW9O34((BuSiO)-Bu-t)(3)Si(CH2-CH=CH2) are orthorhombic, space group P2(1)2(1)2(1) (Ndegrees 19), with lattice constants a = 15.599(2) Angstrom, b = 23.963(5) Angstrom, c = 26.886(1) Angstrom, V = 10.050(3) Angstrom(3), and Z = 4.
