Racemic forms of 1,1 0 -bi-(2-naphthol) (BINOL) monopivalate (rac-1) and its 6-nitro substitute (rac-2) were structurally characterized by X-ray crystallography. Molecules of opposite chirality form dimers in the crystalline state of rac-1 through OAHÁ Á ÁO hydrogen-bonds between the free hydroxy an
In the crystal structure of the title compound, [Cu(C 13 H 9 -N 2 O) 2 ]Á2C 3 H 7 NO, the Cu II ion is coordinated by two N and two O atoms from two deprotonated 2-(1H-benzimidazol-2yl)phenol ligands to give a four-coordinate distorted tetrahedral geometry. The Cu atom lies on a twofold rotation axi
