| Title | K[B6PO10(OH)4]: Ein Borophosphat mit gestreckten Bändern aus Tetraeder-Vierer-Ringen und offen-zyklischen Verzweigungen über planare B203(0 H)2-Gruppen K[B6PO 10(OH)4]: A Borophosphate Containing Rods of Tetrahedral Vierer-Rings with Additional Open-Loop Branchings via Planar B20 3(0 H )2 Groups  | ||
| Abstract | K[B6PO|0(OH)4] was prepared under mild hydrothermal conditions (T = 170 °C) from a concentrated solution of K2B40 7 ■ 4H20 , KH2P 04, and HC1 (18%). The crystal structure of the tetragonal compound was solved by X-ray single crystal methods (space group P 4/ncc, No 130): a = 1209.66(13), c = 759.05(7) pm; Z = 4. The anionic partial structure consists of infinite rods of ^ [B6POl0(OH)4]~ which are built of vierer-rings of alternating B 0 4 and P04 tetrahedra with additional open-loop branchings via planar B20 3(0 H)2 groups at the B 0 4 units by sharing common oxygen functions. Potassium (K+) is located within structural channels running along [001]; the eightfold coordination by oxygen (OH-groups) results in a (slightly) distorted tetragonal antiprism. | ||
