Abstract

Four mixed salts of amino acid L-?histidine comprising hexafluorosilicate anion have been obtained in form of single crystals. These mixed salts are: orthorhombic 2L-?His2+x2ClO4-x?SiF62-?x2H2O (space group P21212, Z=2, a=10.1549(8) Å, b=14.847(1) Å, c=8.7536(7) Å, which is isostructural with recently published 2L-?His2+x2BF4-xSiF62-?x2H2O)?, monoclinic 2L-?His2+x2Cl-?xSiF62-? (space group C2, Z=2, a=27.037(2) Å, b=6.9849(5) Å, c=5.3630(4) Å, ß=91.928(4)?!!!) and isostructural 2L-?His2+x2Br-?xiF62-? (space group C2, Z=2, a=27.063(6) Å, b=7.1013(17) Å, c=5.5076(11) Å, ß=92.141(11)?!!!)?, and triclinic 2L-?His2+xSO42-?xSiF62-?x3H2O (space group P1, Z=1, a=8.5005(17) Å, b=8.7896(18) Å, c=9.7286(19) Å, a=71.49(3)?!!!, ß=92.141(11)?!!!, ?=86.17(3)?!!!)?
