Abstract: 

For the first time dark-red single crystals of K10[Co4O9] were obtained by heating mixtures of KO0.48 and CdO (molar ratio 2.7:1) in closed Co-cylinders at 450-degrees-C during 73 d.

Structure solution and refinement (four-circle diffractometer data, MoKalphaBAR, 2996 out of 2996I(o)(hkl), R = 5.20%, R(w) = 3.03%) confirm the space-group P1BAR and show structural relationship with Na10[Co4O9] [2]. The lattice constants are a = 667.84(5) pm, b = 917.91(9) pm, c = 908.49(7) pm, alpha = 119.400(7)-degrees, beta = 90.851(7)-degrees, gamma = 110.260(6)-degrees, Z = 1. (powder data (Guinier-Simon), standard deviations in parentheses)

MAPLE calculations are made and a comparative survey of MAPLE values of oxocobaltates(II) is given.
