1,1′-Binaphthalene-2,2′-diyl hydrogen phosphate
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 ...
متن کامل(R)-1,1′-Binaphthalene-2,2′-diyl dicinnamate
In the title compound, C(38)H(26)O(4), two cinnamo-yloxy groups are linked in a trans fashion to the two O atoms of optically active (R)-1,10-bi-2-naphthol. The dihedral angle between the mean planes of the two naphthyl groups is 71.8 (1)°. The crystal structure contains inter-molecular C-H⋯O and C-H⋯π inter-actions.
متن کاملTriethylammonium 1,1′-binaphthyl-2,2′-diyl phosphate
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 کاملp-Tolylmethanaminium cyclohexane-1,2-diyl phosphate
In the title mol-ecular salt, C(8)H(12)N(+)·C(6)H(10)O(4)P(-), the cation and anion are connected by N-H⋯O hydrogen bonds. The C atoms of the cyclo-hexane ring are disordered over two sets of sites in a 0.51 (4):0.49 (4) occupancy ratio to generate two superimposed chair conformations. One of the terminal phosphate O atoms is also disordered in a 0.62 (2):0.38 (2) ratio.
متن کاملLecture 11 — March 22 , 2012
Before presenting any integer data structures, we present some models for computations with integers (both to precisely state what we are looking for, and as a framework to prove lower bounds). In each model, memory is arranged as a collection of words of some size (and potentially a small amount of working memory), and a fixed cost is charged for each operation. We also always make the fixed u...
