BaMgF4 und Ba2Mg3F10: Neue Beispiele für Strukturverwandtschaften zwischen Hydriden und FluoridenBaMgF4 und Ba2Mg3F10 wurden durch Tempern stöchiometrischer Gemische der binären Fluoride synthetisiert und an Einkristalldaten verfeinert. BaMgF4 kristallisiert im orthorhombischen BaZnF4-Typ, Raumgruppe Cmc21 (Nr. 36), a = 4.126(1) Å, b = 14.518(4) Å, c = 5.821(2) Å, V = 348.7(2) Å3, Z = 4. Ba2Mg3F10 kristallisiert im monoklinen Ba2Ni3F10-Typ, Raumgruppe C2/m (Nr. 12), a = 18.495(2) Å, b = 5.9497(9) Å, c = 7.8187(9) Å, β = 112.04(1)°, V = 797.5(2) Å3, Z = 4. Die Strukturverwandtschaft zu den analogen Hydriden BaMgH4 und Ba2Mg3H10 wird diskutiert.
Notes:
BaMgF4 and Ba2Mg3F10 were synthesized by sintering stoichiometric mixtures of the binary fluorides and characterized by single-crystal X-ray diffraction. BaMgF4 crystallizes with the orthorhombic BaZnF4 structure type in space group Cmc21 (no. 36), a = 4.126(1) Å, b = 14.518(4) Å, c = 5.821(2) Å, V = 348.7(2) Å3, Z = 4. Ba2Mg3F10 crystallizes with the monoclinic Ba2Ni3F10 structure type in space group C2/m (no. 12), a = 18.495(2) Å, b = 5.9497(9) Å, c = 7.8187(9) Å, β = 112.04(1)°, V = 797.5(2) Å3, Z = 4. The structural relationships to their hydride analogues BaMgH4 and Ba2Mg3H10 are discussed.
