The Interaction of Water with cis and trans {Ru(bpy)2(PTA)2}2+ (PTA = 1,3,5‐Triaza‐7‐phosphaadamantane) Studied by Neutron Scattering and Ab Initio Calculations

“…The most important interatomic distances and angles are given in Table and are similar to those published for complex 2(CF 3 SO 3 ) . The Ru–P and Ru–N bond lengths are somewhat shorter in 2F 2 (Ru–P1 = 2.341(2) Å, Ru1–P2 = 2.332 (15) Å; Ru–N range: 2.092(4) Å‐2.104(4) Å) than in 2CF 3 SO 3 (Ru–P: 2.342(18) Å, 2.353(18) Å; Ru–N range: 2.105(5) Å ‐ 2.110(5) Å), and agree with previously reported bis(bipyridine)‐bis(phosphine)ruthenium complexes …”

Stereochemical Investigation of Palladium(II) Complexes with Phenanthroline Ligands: A Molecular Mechanics Approach

“…[1,7,17] A similar conformation has also been found in the phenanthroline-substituted cations [Pd(3-Rphen) 2 ] 2+ (α = 18.8 and 23.2°, for R = iPr and nBu, respectively), [8] and in the platinum(ii) complex [Pt(phen) 2 ][Cl] 2 · 3H 2 O (α = 20.9°). [18] On the other hand, in the case of [Pd(phen) 2 ][PF 6 ] 2 , the repulsive interactions are partly alleviated by a bending on opposite sides of the π 1 , π 2 and π 1 Ј, π 2 Ј planes (dihedral angles β, βЈ) giving rise to a step geometry (α = 0°, β = βЈ = 16.2°), with the five-membered rings in an envelope conformation. [4] This deformation is accompanied by a tilting, towards the same side, of the π 3 , π 4 planes (dihedral angle γ = 13.4°) so that each phen ligand exhibits a bow conformation, and the cation acquires an overall bow-step shape.…”
