(N,N-Dimethylformamide-κO)bis-(3-hydroxypicolinato- κ2 N,O2)phenylbismuth(III)

Abstract

The title organometallic complex, [Bi(C6H5)(C 6H4NO3)2(C3H 7NO)], features a BiIII atom in a distorted pentagonal-pyramidal coordination by two N,O-donating bidentate 3-hydroxy-picolinate (3-hpic) ligands, one monodentate dimethyl-formamide (dmf) molecule and one phenyl ring. The C atom of the aryl ligand occupies the apical position of the BiCN2O3 coordination polyhedron, while the equatorial plane is formed by one O atom of the dmf ligand and two sets of N and O atoms from the chelating 3-hpic ligands. Inter-molecular secondary Bi⋯O [3.485 (3) Å] and O - H⋯O hydrogen-bonding inter-actions connect the complexes into a three-dimensional network. Intramolecular O - H⋯O hydrogen bonds are also observed.
