Abstract

The title compound ( trivial name terbutylazine), C9H16ClN5, ( I), crystallizes with Z0 = 4 in the space group Pca21, and equal numbers of molecules adopt two different conformations for the ethylamine groups. The four independent molecules form two approximately enantiomorphic pairs. Eight independent N - H center dot center dot center dot N hydrogen bonds link the molecules into two independent chains of R-2(2)( 8) rings, in which the arrangement of the alkylamine substituents in the independent molecules precludes any further crystallographic symmetry. The significance of this study lies in its finding of two distinct molecular conformations within the structure and two distinct ways in which the molecules are organized into hydrogen- bonded chains, and in its comparison of the hydrogen- bonded structure of ( I) with those of analogous 1,3,5- triazines and pyrimidines.
