Crystal and molecular structure of C.I. Solvent Brown 1, 1,3-diamino phenyl azo-2-naphthalene
Abstract
The crystal structure of C.I. Solvent Brown 1, C16H14N4, has been determined by single crystal X-ray diffraction techniques. It crystallises in the orthorhombic system with a = 12.771(1) Å, b = 13.021(1) Å, c = 16.244(3) Å, space group Pcab, (No. 61), Z = 8. The structure has been solved by direct methods and least-squares refinement has been completed on three dimensional data (2561 reflections, MoKα, radiation). The hydrogen atoms have been found but only their positional parameters refined. Final residual 0.096 (all intensity data). The molecule exists as an azo-compound in the trans configuration. The molecules are packed in columns parallel to the a axis, but, unusually, the molecular plane is almost parallel to the column axis. The molecules are linked by one hydrogen bond per molecule almost parallel to the b axis.
