摘要：

Single crystals of Ag0.4Na2.3Ca4.3RuO8 have been prepared by heating Na2O2, CaO and ruthenium in closed silver tubes. Silver took part in the reaction. The crystal structure was investigated by X-ray techniques. Ag0.4Na2.3Ca4.3RuO8 crystallizes with orthorhombic sym metry, space group D-2h(19)-Cmmm; a = 9.255(1), b = 6.683(1), c = 6.696(3) Angstrom, Z = 2. It shows relations to the sodium chloride structure. A statistical distribution of Ag+ and Na+ can be separated in micro space by splitting one oxygen position to give a dumb-bell like O-Ag-O and an octahedral NaO6 coordination.
