Abstract
The crystal structure of a newly synthesized molecular adduct of antimony(III) fluoride with L-phenylalanine of the composition SbF3(C9H11NO2) is determined for the first time (monoclinic crystal system: a = 5.8742(1) Å, b = 6.2079(1) Å, c = 15.5401(3) Å, β = 90.741(1)°, Z = 2, P21 space group). The structure consists of SbF3 molecules and L-phenylalanine bound into polymer chains by bidentate bridging carboxyl groups of amino acid molecules. Weak Sb…F(3)b bonds organize the adjacent chains into polymer ribbons that are bound into layers by N-H…F and N-H…O hydrogen bonds
