(N,N-Dimethyl-formamide-κO)bis-(3-hy-droxy-picolinato-κN,O)phenyl-bis-muth(III).

ABSTRACT

The title organometallic complex, [Bi(C(6)H(5))(C(6)H(4)NO(3))(2)(C(3)H(7)NO)], features a Bi(III) atom in a distorted pentagonal-pyramidal coordination by two N,O-donating bidentate 3-hy-droxy-picolinate (3-hpic) ligands, one monodentate dimethyl-formamide (dmf) mol-ecule and one phenyl ring. The C atom of the aryl ligand occupies the apical position of the BiCN(2)O(3) 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.
