Abstract: 

By "reaction with the wall" we obtained for the first time transparent brown single crystals of Na4[AuCoO5] while heating intimate mixtures of Co3O4, Na2O2, and K2O2 (Co: Na: K = 1.00: 4.91:2.20; 650-degrees-C/44 d) in a sealed gold-tube: monoclinic, P 2(1)/m, with a = 555.69(4)pm, b = 1042.11(8) pm, c 555.69(4) pm, beta = 117.387(5)-degrees, Z = 2.

Characteristic features of Na4[AuCoO5] are meandric chains infinity1[(O2/2(CoO)O2AuO2/2)2].

The structure has been determined by four-circle diffractometer data (Siemens AED 2; Mo-K-alphaBAR, graphite, 881 I(o)(hkl), R = 0.0366, R(w) = 0.0316), parameters as given in the text. The Madelung Part of Lattice Energy, MAPLE, Effective Coordination Numbers, these via Mean Fictive Ionic Radii, and Charge-distribution, CHARDI, are calculated and discussed.
