Summary:The synthesis and crystal structure of new hydrated lead selenite nitrate Pb 4 (SeO 3 ) 3 (NO 3 ) 2 ·2H 2 O ( 1 ) are reported. The crystal structure of 1 ( , a  = 7.2590(2) Å, b  = 7.6454(2) Å, c  = 14.7293(4) Å, α = 84.386(2)°, β = 78.311(2)°, γ = 83.643(2)°, V  = 793.18(4) Å 3 , R 1  = 3.1%) belongs to a new structure type. It is based on a porous framework composed of [Pb 4 (SeO 3 ) 3 ] 2+ layers strongly bound via nitrate anions. Water molecules are located in the channels. Stereochemically active electron pairs of SeO 3 E groups are directed toward each other. The structure of 1 is compared with similar architectures involving Pb 2+ and Se 4+ cations.
