If for a given system two-dimensional (2D ) 119S n /!H heteronuclear shift correlations can be established for long range coupling constants "./(119Sn,'H ) (n = 4, 6), absolute signs of coupling constants /(Sn,Sn) are accessible by this technique for the first time. This has been demonstrated for tetrakis(trimethylstannyl)allene (1) with 2/ ( U9Sn, 117Sn) (>0) and 4/ ( n9Sn, 117Sn) (<0), and fo...
In the title complex, [Cu(C8H11NO5PS)(C18H15P)2], the Cu(I) ion is coordinated by two tri-phenyl-phosphane mol-ecules and two O atoms of the chelating dimeth-yl(phenyl-sulfon-yl)amido-phosphate anion, generating a squashed CuO2P2 tetrahedron. In the six-membered chelate ring, the Cu, P and O atoms are almost coplanar (r.m.s. deviation = 0.024 Å), with the N and S atoms displaced in the same dir...
In the title complex, [RuCl2(CH3CN)3(C18H15P)]·CH3CN, the coordination geometry of the Ru(II) atom is distorted octa-hedral, defined by one P atom from a tri-phenyl-phosphane ligand, three N atoms from three aceto-nitrile ligands and two Cl atoms. The three acetronitile ligands linearly bind to the Ru(II) atom, with Ru-N-C angles of 172.6 (2), 179.9 (2) and 171.4 (2)°.
The title dinitrosyl iron diphosphane complex, [Fe(NO)(2)(C(18)H(12)Cl(3)P)(2)] or Fe(NO)(2)L(2) [L = P(C(6)H(4)-p-Cl)(3)] belongs to the family of metal dinitrosyl compounds with the general formula Fe(NO)(2)(L)(x), referred to collectively as dinitrosyl iron compounds (DNICs). The iron atom is tetra-hedrally coordinated by two phosphane ligands and two NO groups with Fe-N-O bond angles of 178...
The reaction of the primary phosphane (ferrocenylmethyl)phosphane [PH(2)CH(2)Fc, ] with an equimolar amount of [M(cod)Cl(2)] (cod = 1,5-cyclooctadiene, M = Pd, Pt) gave the unusual monobridged M(ii) dinuclear complexes of formula [(cod)ClM(micro-PHCH(2)Fc)M(PH(2)CH(2)Fc)Cl(2)] [M = Pt, ; M = Pd, ]. The mechanism leading to and involves the preliminary formation of cis-[M(PH(2)CH(2)Fc)(2)Cl(2)] ...
Neutral and cationic N-methyl- N-phenyl-2-aminobiphenyl methanesulfonate palladacycles stabilized with dialkylterphenyl phosphanes have been prepared characterized. structures are favored the less bulky phosphane PMe2ArXyl2, L1, while more sterically demanding ligands PiPr2ArXyl2, L3, PCyp2ArXyl2 (Cyp = cyclopentyl), L4, lead to complexes in which exhibits a bidentate ?1-P, ?1-Carene coordinati...
