Synthesis and crystal structure of bis(triphenylphosphine)gold tricyanomethanide, [(PPh3)2Au]+ [C(CN)3]−

Carboranyl C-σ-bonded and C-functionalized carboranes as ligands in gold and silver chemistry

“…2a). The ortho isomer o-(CH) 2 B 10 H 10 reacts with [Au 3 -(l-O)(PPh 3 ) 3 ] + and NaH, leading to the monosubstituted [Au-(o-C 2 B 10 H 11 )(PPh 3 )] [7]. Table 1 resumes some crystallographic data.…”

“…anionic ligand [7, ) 2 -7,8-C 2 B 9 H 10 ] À . Thus, three-or four-coordinated neutral products (Scheme 5) [13,14] have been afforded by reaction, in refluxing ethanol, of the closo-diphosphine with either: the corresponding halogold precursor or the perchloratesilver compound or a mixture of AgNO 3 and the corresponding ligand.…”

“…Some of them have also been obtained from the reaction of [AgCl(PPh 3 ) 2 ] with the corresponding closo dithioether in refluxing ethanol. Different stoichiometries [Ag(L)] [L = (7, S)-7,8-C 2 B 9 H 10 ) À (L s2c5 ) À ; (7, ) 2 S}-7,8-C 2 B 9 H 10 ) À (L s2c6 ) À ; (7, CH 2 OCH 2 CH 2 OCH 2 CH 2 S}-7,8-C 2 -B 9 H 10 ) À (L s2c12 ) À ; (7, CH 2 OCH 2 CH 2 OCH 2 CH 2 OCH 2 -CH 2 S}-7, 8-C 2 B 9 H 10 ) À (L s2c15 ) À ], [Ag(L)(PPh 3 )] [L = (L s2c5 ) À ; (L s2c6 ) À ; (7, CH 2 OCH 2 CH 2 S}-7,8-C 2 B 9 H 10 ) À (L s2c9 ) À ; L s2c12 ;7, …”

Structure of [Au(PPh3)2][C(CN)3]

“…The structure of one crystal form of Au(PPh3)2(TCM) (space group C2/c) has been reported (Baukova et al, 1989). Here we report the structure of another form (space group P2~/c) in which the molecular structure and the geometry are quite different.…”

Structural and Spectroscopic Characterisation of Linearly Coordinated Gold(I) Tribenzylphosphane Complexes

“…[18] With an initial focus on gold(I) as the metal atom in complexes of the form [M(PR 3 ) 2 ]X and [(R 3 P)MX], an array of established structural data is presented in Table 1 and 2, respectively; a datum value for the Au-P distance in [Au( PPh 3 ) 2 ] + is taken as 2.31 Å.
