For the first time, new hybrid organic-inorganic layered zirconium pentafluorides of methylammonium, glycinium, and β-alanine with the composition (CH₃NH₃)ZrF₅·0.5H₂O, (H₃NCH₂COOH)ZrF₅·2H₂O, and (H₃N(CH₂)₂COOH)ZrF₅ are synthesized and their structures are analyzed. In the studied compounds, CN of the Zr atom is 8, and its coordination polyhedron represents a dodecahedron sharing its 6 vertex with three neighboring Zr polyhedra. The Zr dodecahedra are joined with each other in planar netlike anion layers of the composition . The anion layers are hydrogen bonded into a three-dimensional structure by H₂O cations and molecules.
