Trigonal prismatic molecules

The Gd + complex of a diamide (22) has an octadentate ligand in a nine-coordinate tricapped trigonal prismatic molecule with one coordinated water molecule. ... [Pg.145]

Molecules of tris(diphenylacetylene)tungstenmonocarbonyl (85) have a capped trigonal-prismatic (Cj, ) structure. The geometry of the acetylene groups is considerably altered by co-ordination, the C—C—CPh angles being ca. 140°. ... [Pg.129]

The diethylammonium salt of the tris(tetraphenyldisiloxanediolato)zirconate(IV) anion (33) has been obtained in very low yield from the reaction of [Zr(NEt2)4] with diphenylsilanediol in THF. The ligand results, under the basic reaction conditions, from condensation of two Ph2Si(OH)2 molecules. Anion (33) has an octahedral tris-chelate structure with a twist angle (46.9°) that indicates some distortion towards trigonal prismatic geometry.466... [Pg.418]
