“…Nitratobis(triphenylphosphine)silver(I), the monomeric form corresponding to the dimeric title compound, has previously been studied as two modifications: the unsolvated form (Barron, Dyason, Healy, Engelhardt, Skelton & White, 1986) and a benzene solvate (Harker & Tiekink, 1989). A dimer (2), structurally analogous to the title compound, has also been characterized; this involves trimethylphosphite rather than triphenylphosphine (Meiners, Clardy & Verkade, 1975).…”

“…The molecule ( Fig. 1) possesses crystallographic twofold symmetry, the axis passing through the atoms N(1), O(2), N(2) and O(4), whereas the corresponding complex (2) (Meiners et al, 1975) displayed inversion symmetry; in both cases the central four-membered ring is exactly planar. In (1), the nitrate ions are also planar by imposed symmetry and are almost coplanar with the central ring [dihedral angles 6 and 4 ° for the nitrates at N(1) and N(2), respectively].…”

“…Phosphorus-based compounds offer a wide range of steric properties and basicities because of the variety of accessible substituents. − In addition, many phosphorus-based compounds bind strongly to transition metals. As a result of their coordinating ability and highly tunable stereoelectronic character, phosphorus-based compounds are among the most heavily utilized class of ligands in coordination chemistry and homogeneous catalysis. − ,− ,,− Several studies have quantified the steric and donor properties of a wide range of phosphorus-based ligands. ,,− ,− For example, the classic work by Tolman established the comparison of the steric properties of phosphorus ligands using cone angles . Recently, predicting the steric properties of phosphorus-based ligands has been improved using crystallographic data and computer modeling software. ,, The donor abilities of phosphorus ligands have been studied using CO absorption energies for metal carbonyl complexes with phosphorus ligands [e.g., Ni(CO) 3 L where L = phosphite, phosphine, etc.]…”

The complexes TpRu[P(OCH(2))(2)(OCCH(3)](PPh(3))Cl (2) [Tp = hydridotris(pyrazolyl)borate; P(OCH(2))(2)(OCCH(3)) (1) = (4-methyl-2,6,7-trioxa-1-phosphabicyclo[2,2,1]heptane] and TpRu(L)(PPh(3))Cl [L = P(OCH(2))(3)CEt (3), PMe(3) (4) or P(OMe)(3) (5)], (η(6)-C(6)H(6))Ru(L)Cl(2) [L = PPh(3) (6), P(OMe)(3) (7), PMe(3) (8), P(OCH(2))(3)CEt (9), CO (10) or P(OCH(2))(2)(OCCH(3)) (11)] and (η(6)-p-cymene)Ru(L)Cl(2) [L = P(OCH(2))(3)CEt (12), P(OCH(2))(2)(OCCH(3))P(OCH(2))(2)(OCCH(3)) (13), P(OMe)(3) (14) or PPh(3) (15)] have been synthesized, isolated, and characterized by NMR spectroscopy, cyclic voltammetry, mass spectrometry, and, for some complexes, single crystal X-ray diffraction. Data from cyclic voltammetry and solid-state structures have been used to compare the properties of (1) with other phosphorus-based ligands as well as carbon monoxide. Data from the solid-state structures of Ru(II) complexes show that P(OCH(2))(2)(OCCH(3)) has a cone angle of 104°. Cyclic voltammetry data reveal that the Ru(II) complexes bearing P(OCH(2))(2)(OCCH(3)) have more positive Ru(III/II) redox potentials than analogous complexes with the other phosphorus ligands; however, the Ru(III/II) potential for (η(6)-C(6)H(6))Ru[P(OCH(2))(2)(OCCH(3))]Cl(2) is more negative compared to the Ru(III/II) potential for the CO complex (η(6)-C(6)H(6))Ru(CO)Cl(2). For the Ru(II) complexes studied herein, these data are consistent with the overall donor ability of 1 being less than other common phosphines (e.g., PMe(3) or PPh(3)) or phosphites [e.g., P(OCH(2))(3)CEt or P(OMe)(3)] but greater than carbon monoxide.
