Crystal structure of [1,1,4,4-tetraethylpiperazinium] dichloride–4-(p-nitroaniline)

Abstract

The crystal structure of [1,1,4,4-tetraethylpiperazinium]dichloride–4-(p-nitroaniline), C36H52Cl2N10O8[(C12H28N2)-Cl2,4(C6H6N2O2)], has been determined by use of three-dimensional equi-inclination Weissenberg X-ray diffraction data with 1447 visually estimated reflections. The orthorhombic unit cell, space group Pbca, (D2n15) has dimensions a= 22·65(2), b= 16·37(2), c= 11·33(2)Å, with Z= 4. The structure was solved by direct methods (tangent formula) and refined by full-matrix least-squares techniques to R 0·16. The 1,1,4,4-tetraethylpiperazinium ion is at a centre of symmetry. The structure consists of alternate blocks of p-nitroaniline and [1,1,4,4-tetraethylpiperazinium] dichloride along the a direction. Hydrogen bonds link the chloride ions to pairs of p-nitroaniline molecules.
