N2 - Single crystals of Pb 3O 2(SeO 3) have been prepared hydro thermally at 230°C. The structure (orthorhombic, Cmc2 1, a = 10.529(2), b = 10.722(2), c = 5.7527(12) Å, V = 649.5(2) Å 3) has been solved by direct methods and refined to R 1 = 0.059 on the basis of 615 unique observed reflections (|F o| = 4σ F). The structure is based upon double [O 2Pb 3] 2+ chains of edge-sharing [OPb 4] 6+ tetrahedra. These [O 2Pb 3] 2+ chains run parallel to [001], and their planes are parallel to (010). The pyramidal (SeO 3) 2 anions are located between the chains; their triangular oxygen atom bases lie parallel to (001) and all (SeO 3) 2- groups are pointing in the same direction. A short compilation of [O 2M 3] chains of oxocentred M 4 tetrahedra in minerals and inorganic compounds is provided.
