Co-ordination of (o-aminophenyl)diphenylphosphine in complexes containing the [Mv= O]3+(M = Tc or Re) core

Monodentate imido and bidentate aminophenolate coordination of 2-aminophenol in rhenium(V) complexes

“…The iodide is coordinated trans to the neutral N(1) of Hap, with which it makes an average angle of 165.7(1) .The ap ligand acts as a monodentate dianion, with coordination to rhenium through the doubly deprotonated imido nitrogen N(2) only and the O(2)H hydroxyl group is not coordinated. The Re-N(2)-C(7) average bond angle of 170.5(4) illustrates a significant deviation from linearity of the coordination mode of the triply bonded phenylimido unit, and the average Re-N(2) distance of 1.723(4) Å agrees with values found in other rhenium(V)-phenylimido octahedral complexes[17,18]. The phenylimido moiety is virtually perpendicular to the mean equatorial plane (dihedral angle 174.7 ).…”

Phosphanyl-Amino Complexes of Nickel(II): Synthesis and Structure

“…Conversely, the coordination chemistry of this important result. 2-(diphenylphosphanyl)aniline [9] has been widely investiThe various properties of phosphanyl-amino ligands gated because of its ability to behave as a bidentate chelat-prompted us to undertake a systematic study aimed at preing amino [10] , amido [11] , or imido [12] ligand. This behavior paring both neutral and cationic nickel(II) complexes of the has been further developed in the synthesis of new macro-type shown in Scheme 1 and to evaluate the potential of cyclic chelate compounds such as P 2 N 2 ligands, which have the cationic species as "SHOP"-type catalysts [16] .…”

The reaction of [ReIIICl3(t-BuNC)(PPh3)2] with aniline derivatives: Isolation of imido-Re(V) complexes and a Re(III) complex containing iminobenzoquinonate as ligand

“…These lengths are within the range expected for Re(V)-imido bonds [21]. The X-ray Re-C bond lengths are about 2.03 Å (computed about 2.00 Å) and they are significantly shorter than those expected for a Re-C single bond (2.13 Å) and longer than the distance expected for a double bond (1.91 Å), indicating a measure of some double bond character in this bond [37]. The Re-Cl and Re-P bond distances are normal.…”
