摘要：
The hitherto unknown compound NaCu2O2 was prepared by a closed-tube technique. X-ray investigations of single crystals led to orthorhombic symmetry, space group D2h16 (Pnma) (no. 62), a = 6.183 angstrom, b = 2.935 angstrom, c = 13.209 angstrom, Z=4. Cu+ exhibits dumb-bell-like, Cu2+ square planar and Na+ square pyramidal coordination with oxygen. NaCu2O2 is isotypic with LiCu2O2. The crystal chemistry is discussed with respect to LiCu2O2 and TlCu2O2.
