Abstract
L-arginine fluoride is a promising compound that exhibits nonlinear optical properties. It efficiently converts two single photons of the same polarization and frequency ω to one photon of frequency 2ω (type I phase matching). C6H15N4O2 +F− is monoclinic, space group P21, a = 5.4475(4) Å, b = 8.5133(6) Å, c = 10.2195(7) Å, β = 93.475(6)°. The cation has a zwitterionic form, protonated at both the guanidyl and amino groups. The arginine Cγ atom is in a trans position to the carboxyl group. A complex three-dimensional hydrogen bond network links the anions and cations together.
