“…An interesting feature of the trans structure I is that the axial sites are inequivalent due to the arrangement of the phenyl groups; site X is "surrounded" by four phenyl groups whereas site Y has only two phenyl groups near it. The crystal structures of trans-[FeH(N7)L]Br (11) and trans-RuC12L (12) clearly demonstrate this feature. The dinitrogen ligandis located in the four-phenyl binding site in the former complex.…”

“…In an extreme reversal of this effect, the large PPh3 ligands in the trihydride complex [ o s (~)~( P P h~)~] + prevent the attainment of an octahedral geometry and therefore the formation of a dihydrogen ligand (46). The shortening cannot be attributed to a decrease in backbonding to the H2 caused by lower energy d electrons in the tetraphos complexes because, in every case examined, the tetraphos complex is more reducing than the corresponding dppe complex ( Similarly reaction [4] implies that the osmium dihydrogen complex also reacts stereoselectively with chloride to give the major isomer as indicated in reaction [12].…”

“…Therefore octahedral nzeso-tet-1 complexes adopt either structure trans-I or cis-p-11. This isomerism was not fully appreciated in early studies of its coordination chemistry (9)(10)(11)(12) until the work of Brown and Canning (13). Taqui Khan and Mohiuddin partially characterized a complex [RuCl(tet-l)]Cl, which was a one to one electrolyte in nitromethane (9).…”

Can. J. Chem. 72,547 (1994). The synthesis and properties of dihydrogen complexes trans-[MH(H2)L]+, M = Fe, Ru, Os, which contain the ligand mesotetraphos-1, S,R-Ph2PCH2CH2P(Ph)CH2CH2P(Ph)CH2CH2PPh2 (L) are described. There are interesting possibilities of isomerism in such trans complexes because the axial binding sites at the metal are different, one being surrounded by four phenyl groups and the other by two phenyl groups. The osmium complex is prepared in an unusual reaction of ci.~-p-Os(Cl)~L with HI, (1 atm) and NaBPh4 (1 mol) in THF or by the reaction of trans-OsH(C1)L with NaBPh4 and H2. The iron and ruthenium complexes were made by a reaction of HBF4 with complexes t r a n~-M ( H )~L that have inequivalent trans hydrides. The ruthenium complex was also prepared starting from isomers of t r a n s -R U H ( C~) L .~T~~ H-H distance in the rapidly spinning dihydrogen ligand has been calculated from Tl(min) data to be 0.

In [FeH(N2)(Pa)]Br (3) (Ghilardi, Midollini, Sacconi & Stoppioni, 1981) and [RuC12(P4)] (4) (Rivera, De Gil & Fontal, 1985) all P atoms of meso-P4 are located within the equatorial planes of the octahedral configurations and the central atoms are shifted out of these planes in the same directions as in (1) [Fe atom in (3): 0.343, Ru atom in (4): 0.125 A]. In (3) the enhanced displacement of the Fe atom from the equatorial plane is a result of the steric differences of the axial N2 and H ligands.…”

Abstract. meso-[Pt(C42H42P4)][B(C24H2o)]. The thermodynamic destabilization of the square-planar arrangement of the title compound is compared with the destabilization of the corresponding chiral form and differences are discussed. Short intramolecular contact distances lead, in both cases, to the occurrence of related five-coordinate trigonal-bipyramidal and distorted tetrahedral compounds, thus releasing the strain of a planar P4 configuration.
