Capped trigonal prismatic

MFg] , capped trigonal prismatic [MFv], and even square-antiprismatic [MFg] salts can all be isolated. By contrast with the fluorides, aqueous solutions of MCI5 and MBrs (M = Mb, Ta) yield only oxochloro- and oxobromo-complexes, though the application of non-aqueous procedures allows their use as starting materials. [Pg.994]

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]

Examples of monomeric Mo11 complexes are much less common. It has been demonstrated that the [Mo(CN)7]5 ion has a pentagonal bipyramidal structure. Other examples are nitrile (i.e. isocyanide) complexes [Mo(CNR)7]2+, which has a capped trigonal prismatic structure, and the diarsine complex [Mo(diars)2X2]. [Pg.1230]

Mo(CNR)7]2+ [Mo(CNR)s(chel)]2+ (chel = dppm, dppe, bipy, etc.)-, [MoCl(CNBut)4(bipy)]+ Mo(CNC6H11)s(bipy)]2+ [Mo(CNR)3(bipy)2]2+. They are generally prepared by displacement of CO, bipy, OAc, NO or other ligands from a suitable precursor by RNC and have capped octahedral or capped trigonal prismatic structures.10,70... [Pg.1283]

In the calcium polyiodide compound [Ca(H2O)7](I10) the stereochemistry appears to be intermediate between a capped octahedron and a pentagonal bipyramid, whereas [Sr(H20)7](I12) and [Ca(H20)7]2[CdgCl16(H20)2]-H20 contain capped trigonal prismatic cations.246 247... [Pg.72]
