Abstract: 
We obtained previously unknown K3{Li[IrO4]} in the form of dark-red elongated single crystals, by heating well-ground mixtures of Li2IrO3 and KO0.51 (molar proportions Ir:K, 1.00.3.76) in an ''Ag cylinder'' (at 1073 K for 71 days). K3{Li[IrO4]} crystallizes as mC36 in the space group C2/c, with a = 1067.29(9) pm, b = 986.36(8) pm, c = 587.70(5) pm and beta = 103.938(8)degrees; Z = 4. Refinement of the structure with 949 reflections (F(o) > 3sigma(F(o))) from 1032 independent reflections (merged from 4137 I(o)(hkl)) gave R = 0.0351 and R(w) = 0.0378. The structure is characterized by Vierer single chains infinity1[(O2/2LiO2IrO2/2)2] isolated from one another. Their arrangement corresponds to the configuration of a densest packing of ''tree-trunks''. The effective coordination numbers, mean fictive ionic radii and the Madelung part of the lattice energy, as well as the charge distribution are calculated and discussed.
