Abstract: | The crystal structure of an antimony(III) fluoride complex of the composition (C5H12NO2)SbF4·H2O (I) involving a cation of α-amino isovaleric acid (DL-valine, Val) is determined. Crystals are monoclinic: a = 12.2024(2) Å, b = 6.1636(1) Å, c = 15.5167(3) Å, Z = 4, space group P21/c. The structure is formed of DL-valinium (C5H12NO2)+ cations, complex SbF4]nn? anions having a polymeric chain structure, and crystallization water molecules. The SbF4]nn? complex anions consist of trigonal SbF4E bipyramids joined together by asymmetric bridging Sb–F(3)···Sb bonds. The structural units are organized into a threedimensional framework via N–H···F, N–H···O, and O–H···F hydrogen bonds. |
