The reaction of [Ru3(CO)12] with bis(diphenylphosphino)amine. The crystal and molecular structure of [Ru3(CO)10(dppa)] and [Ru3(CO)8(dppa)2]

Alkali Metal and Alkaline Earth Metal Complexes with the Bis(borane‐diphenylphosphanyl)amido Ligand – Synthesis, Structures, and Catalysis for Ring‐Opening Polymerization of ϵ‐Caprolactone

“…These μ-bis(dialkylphosphanyl)-alkane]bis[pentacarbonyl-metal(0)] complexes (CO) 5 MR 2 P(NH)-PR 2 M(CO) 5 (M = Cr, Mo, W) were synthesized from the reaction of M(CO) 5 (CH 3 CN) with the dppa ligand. [2,[5][6][7] The chalcogen (sulfur and selenium) functionalized dppa derivatives were also well defined to stabilize metal complexes by the formation of chalcogen metal bonds. [8,9,10] These unique ligands are potentially capable of coordinating through the hard nitrogen and phosphorus donor atoms along with the soft chalcogen donor atom to provide the highest coordination sphere of the metal ion required for its stabilization.…”

Group VIII transition metal complexes with the chiral diphosphazane ligand (S)-α-(Ph2P)2N(CHMePh): Synthesis and structural characterization

“…In a similar form to the widely used bis(diphenylphosphino)methane (dppm, CH 2 (PPh 2 ) 2 ) the phosphinoamine ligands can bind to metal atoms in different ways: monodentate, chelating or bridging [1][2][3][4][5][6][7][8][9][10][11][12][13][14].…”

Synthesis and Molecular Structure of [Ru3(CO)10(μ‐dppa)] (dppa = Ph2PN(H)PPh2) Provided by Its Dioxane Solvate

“…The two chemically equivalent P nuclei resonated in the 31 P{ 1 H} NMR spectrum as singlet at δ = 69.6 ppm (CDCl 3 ). [7] For our compound 1 compare these data in the Experimental Section. Furthermore, a 13 C{ 1 H} NMR spectrum of 1 in CD 2 Cl 2 was recorded exhibiting the following reso-…”

“…a deeper detail. [7] Furthermore, the authors obtained the species [Ru 3 (CO) 10 (μ-dppa)] and [Ru 3 (CO) 8 (μ-dppa) 2 ] as a mixture of both complexes (30 and 60 %), whereas the mixture had to be separated by chromatographic workup. [7] Finally, these authors obtained single-crystals of [Ru 3 (CO) 10 (μ-dppa)] from chloroform suitable for X-ray diffraction and determined its molecular structure.…”
