Crystal structure of a beryllium-potassium polyphosphate: BeK(PO3)3
Abstract
Chemical preparation and crystal structure of a beryllium-potassium long chain polyphosphate, BeK(PO3)3, are reported. Space group is P212121 with the following unit-cell dimensions: a = 7.844(1), b = 8.610(2), c = 11.399(4) Å; Z = 4. The final R value is 0.023 for a set of 1572 independent reflexions.
The (PO3)∞ chains run along the [unk] axis with a period of six tetrahedra. The atomic arrangement is mainly characterized by a three-dimensional network of PO4 and BeO4 tetrahedra built up by sheets of six-tetrahedron rings (P5Be or P4Be2) linked by Be – O – P bonds. Potassium atoms are located in channels parallel to the [unk] axis.
