catena-Poly(22′-bipyridine-κ2 NN′)(dimethyl sulfoxide-κO)(nitrato-κ2 OO′)bis­muth(III)-μ-5-carb­oxy­benzene-13-dicarboxyl­ato-κ4 O 1 O 1′ :O 3 O 3′ dimethyl sulfoxide monosolvate

摘要

The polymeric title compound, {[Bi(C9H4O6)(NO3)(C10H8N2)(C2H6OS)]·C2H6OS}n, was obtained by the reaction of bis­muth(III) nitrate, bipyridine (bpy) and 1,3,5-benzene­tricarb­oxy­lic acid (H3BTC). The Bi^III ion is coordinated in a distorted tricapped trigonal-prismatic geometry, defined by two N atoms of the bipy ligand, four O atoms of two HBTC²⁻ anions, two O atoms of a nitrate anion and one O atom of a dimethyl sulfoxide ligand. The crystal packing is stabilized by O—H⋯O and C—H⋯O hydrogen bonds. The S atom of the non-coordinating dimethyl sulfoxide mol­ecule is disordered over two sets of sites with refined site-occupancies of 0.430 (19) and 0.570 (19).
