Abstract:	The synthetic compound Pb₆Cu(AsO₃)₂Cl₇ crystallizes in space group R witha₀=9.8614(4),c₀=17.089(2)Å,Z=3. The crystal structure, determined by single crystal X-ray work, is a typical layer structure. Complex Pb₆(AsO₃)₂Cl₆ layers are combined via monovalent Cu and Cl atoms. A novel element within the structure is a [Cl₃Cu(I)-As(III)O₃] group with the interatomic distances (Å): Cu-Cl=2.44 (3×), As-O=1.76 (3×), Cu-As=2.34 (1×).

Keywords:	Crystal structure Arsenite Cl₃Cu(I)-As(III)O₃ complex Pb₆Cu(AsO₃)₂Cl₇ structure
