Abstract
KCo2O4, RbCo2O4 und CsCo2O4 zeigen gleiche Substruktur, jedoch jeweils mehrere verschiedene überstrukturen.
Symmetrie und Abmessungen der Subzellen: D
−P63 22: KCo2O4: a = 2,845, c = 12,359 Å; RbCo2O4: a = 2,838, c = 13,043 Å; CsCo2O4: a = 2,84, c = 13,98 Å. Die Substruktur von KCo2O4 weist längs [0 0.1] eine O2− Abfolge entsprechend AABB…auf. Co ist verzerrt oktaedrisch, K trigonal-prismatisch von Sauerstoff koordiniert (127 Reflexe h01
h21, R = R′ = 10,68%).
On Oxocobaltates AxCo2O4 (A = Cs, Rb, K)
KCo2O4, RbCo2O4 and CsCo2O4 have the same substructure but several different superstructures. Symmetry and crystal spacings of the subcells see “Inhaltsübersicht”.
The substructure of KCo2O4 consists of successive O2−−layers along [0 0.1] according to AABB… Co has a distorted octahedral, K a trigonal-prismatic coordination of oxygen (127 reflexions h 01
h21, R = R′ = 10.68%).
