- Abstract
Mixed salts of amino acids with different anions are of considerable interest from chemical and structural points of view and also as a source of new materials the properties of which can be controlled by appropriate choice of anions. Four such crystals, L-His2+·Cl-·HSO4- (P212121, Z=4), L-Arg2+·NO3-·ClO4- (d-form, P21, Z=4), L-Arg2+·F-·NO3- (P1, Z=2), 2L-Arg2+·(F-?HF)·3NO3- (P212121, Z=4), have been characterized structurally and by IR and Raman spectra. The hydrogen bond between the carboxyl group and the fluoride ion (2.371(3) Å) in the structure of L-Arg2+·F-·NO3- is among the shortest known O-H?F type hydrogen bonds. The O-H?F hydrogen bond in the structure of 2L-Arg2+·(F-?HF)·3NO3- is even shorter (2.341(2) Å) and thus belongs to the shortest contacts among both ?–??F and F–-?O types hydrogen bonds.
