| Abstract: | Single crystals of Sr2CuO2Cl were prepared in a closed system of Ag- and quartz-tubes. The colorless crystals are extremly sensitive against moisture. X-ray investigation proves a trigonal symmetry (a=400.3;c-2767.9 pm, space group P3121-D

). Sr2+ has a distorted octahedral coordination of 3 O2– and 3 Cl–. Cu+ shows a dumbbell like O2– surrounding. The O-Cu-O bond angle (176.5°) differs from the usually value (180°). |
