Sun ZH, Fan JD, Zhang GH, Wang XQ, Xu D - Acta Crystallogr Sect E Struct Rep Online (2008)

Bottom Line: A three-dimensional network of hydrogen bonds is observed, forming a closed ring.The F atoms of the trifluoro-acetate anion are disordered over two sites with site occupancies of 0.423 (18) and 0.577 (18).The asymmetric unit consists of two cations and two anions.

ABSTRACT
Ions of the title compound, C(6)H(15)N(2)O(2) (+)·C(2)F(3)O(2) (-), a new organic nonlinear optical crystal, are linked by N-H⋯O hydrogen-bonding inter-actions. Both the amino groups of the l-lysinium cation are protonated. A three-dimensional network of hydrogen bonds is observed, forming a closed ring. Inter-molecular N-H⋯O hydrogen bonds involving l-lysinium cations and trifluoro-acetate anions link the ions into extended chains which run parallel to the [010] direction. The F atoms of the trifluoro-acetate anion are disordered over two sites with site occupancies of 0.423 (18) and 0.577 (18). The asymmetric unit consists of two cations and two anions.
