Abstract

The crystal structures of five new glycine (H₂N–CH₂–COOH) metal halogenide compounds were determined by single crystal X-ray diffraction. Three of them are monoclinic phases, GlycineCaCl₂ · 3 H₂O (space group P2₁/c, a = 9.964(2), b = 6.868(1), c = 13.959(3) Å, β = 104.11(3)°, R1 = 0.024), GlycineZnCl₂ · H₂O (space group P2₁/a, a = 7.868(1), b = 9.124(1), c = 10.645(1) Å, β = 103.51(1)°, R1 = 0.026) and Glycine₂ZnCl₂ · 2 H₂O (space group C2/c, a = 14.444(1), b = 6.916(1), c = 12.968(1) Å, β = 117.90(3)° R1 = 0.033), two of them are orthorhombic phases Glycine₃CeCl₃ · 3 H₂O (space group P2₁2₁2₁, a = 4.788(1), b = 12.074(2), c = 30.949(6) Å R1 = 0.034) and Glycine₂CaI₂ · 3 H₂O (space group Pca2₁, a = 13.059(3), b = 9.862(2), c = 22.724(5) Å R1 = 0.023). The atomic arrangements as well as aspects of the crystal chemistry of these compounds are presented.
