Show affiliationsThe two-leg ladder SrCu2O3 belongs to the homologous series Srn −1CunO2n−1 and was first synthesized by Hiroi et al (Hiroi Z, Azuma M, Takano M and Bando Y 1991 J. Solid State Chem. 95 230). Due to the massive reaction of the sample material with the crucible (Au or Pt), only short reaction times up to 30 min have been used typically. We suggest an improved composite crucible with a single-crystalline MgO inset in a sealed Pt capsule and demonstrate its capability for single-crystal growth of SrCu2O3. Experiments with a typical duration of 15 h were conducted at pressures between 3 and 6 GPa at temperatures between 950 and 1500°C. Slow cooling of the melt effected directed growth of the first SrCu2O3 milimetre-sized single crystals.
