抄録

Single crystals of [Sr₂Cu₂O₃]x15[CuO₂] (x= 0.696) were successfully obtained using KC1 as a flux. This compound takes a composit crystal structure. The first subsystem is [Sr₂Cu₂0₃]and the second one [Cu0₂]. Both subsystems h ave an orthorhombic structure with superspace group mArs The compound has mutually incommensurate periods along the c axis. The lattice prameters are a= 11.457( 5 )Å, b=13.409( 9 ) Å, c1= 3.935( 3 ) Å, c2= 2.740 ( 2 ) Å. Characteristic features of this compound are chains and sheets composed of Cu and O atoms.
