چکیده
The title compound, racemic bnppa, C(20)H(13)O(4)P, crystallizes with four mol-ecules in the asymmetric unit. Two independent centrosymmetric O-H⋯O hydrogen-bonded tetra-mers, each involving two of the symmetry-independent mol-ecules in the asymmetric unit generate the packing motif in the crystal structure. The hydro-phobic parts of the tetra-mers connect to their neighbours via C-H⋯π and π-π inter-actions [3.899 (2), 3.895 (2) and 3.803 (2) Å within the symmetric unit, 3.851 (2), 4.000 (2), 3.988 (2) and 3.905 (2) Å across centres of symmetry].

In the crystal structure of the title compound, C(6)H(16)N(+)·C(20)H(12)O(4)P(-), an N-H⋯O inter-action links the cation to the anion. The N atom in the triethyl-ammonium cation exhibits a trigonal-bipyramidal coordination geometry and forms an N-H⋯O inter-action with one phosphate O atom of the 1,1'-binaphthyl-2,2'-diyl phosphate ligand. A bifurcated C-H⋯O inter-action with the other phosphate...
متن کاملSecondary interactions or ligand scrambling? Subtle steric effects govern the iridium(I) coordination chemistry of phosphoramidite ligands.
The like and unlike isomers of phosphoramidite (P*) ligands are found to react differently with iridium(I), which is a key to explaining the apparently inconsistent results obtained by us and other research groups in a variety of catalytic reactions. Thus, the unlike diastereoisomer (aR,S,S)-[IrCl(cod)(1 a)] (2 a; cod=1,5-cyclooctadiene, 1 a=(aR,S,S)-(1,1'-binaphthalene)-2,2'-diyl bis(1-phenyle...
