The title organometallic complex, [Bi(C6H5)(C6H4NO3)2(C3H7NO)], features a BiIII atom in a distorted pentagonal-pyramidal coordination by two N,O-donating bidentate 3-hydroxypicolinate (3-hpic) ligands, one monodentate dimethylformamide (dmf) molecule and one phenyl ring. The C atom of the aryl ligand occupies the apical position of the BiCN2O3 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. Intermolecular secondary Bi⋯O [3.485 (3) Å] and O—H⋯O hydrogen-bonding interactions connect the complexes into a three-dimensional network. Intramolecular O—H⋯O hydrogen bonds are also observed.

The initial reactants used were obtained commercially from Strem and Sigma-Aldrich. In a nitrogen filled glove-box, triphenylbismuth (440 mg, 1.0 mmol) and 3-hydroxypicolinic acid (420 mg, 3.0 mmol) were ground together for 30 min resulting in a light-grey powder. The mixture was placed in a Schlenk tube and heated upon stirring at 120 °C for 90 min. The resulting grey powder is treated with dry dmf, then filtered. The filtered solution is concentrated to ~1/4 of its initial volume and left for crystallization at room temperature. Crystals suitable for single-crystal X-ray crystallography were formed in 4 weeks.
The H atoms bound to O13 and O23 were located in a difference map and their coordinates were refined with Uiso(H) values of 1.2Ueq (O). C-bound H atoms were located in calculated positions and constrained to ride on their parent atoms at distances of d(C-H) = 0.93Å, Uiso=1.2Ueq (C) for aromatic and 0.96Å, Uiso = 1.5Ueq (C) for CH3 atoms
The title compound, (I), was obtained from the solvent-free reaction of BiPh3 and 3-hydroxypicolinic acid (3-hpicH) with subsequent recrystallization from dimethylformamide (dmf) (see Experimental). Single-crystals suitable for X-Ray crystallography were obtained at room temperature from the concentrated dmf solution. The
of (I) revealed a mononuclear compound, in which the BiIII atoms are hexa-coordinated in a distorted pentagonal pyramidal geometry with two N and two O atoms of N,O-chelating 3-hpic ligands and one dmf O donor in the equatorial plane (Figure 1). The axial position of the pentagonal pyramid is occupied by a carbon atom of the aryl group (Bi1—C41 = 2.245 (4) Å). Both picolinate ligands are monodeprotonated and display N,O-chelation through the pyridine N and carboxylate O atoms. There is an important asymmetry in the 3-hpic coordination to BiIII (Bi1—N1 = 2.660 (3) Å, Bi1—O11 = 2.348 (3) Å; Bi1—N2 = 2.488 (3) Å, Bi1—O21 = 2.382 (3) Å). The O atom of the coordinated dmf molecule (Bi1—O31 = 2.534 (3) Å) completes the equatorial plane of the pyramid.There is a relatively large variation in the equatorial angles of the pyramid (64.97 – 77.37°) due to the difference in Bi—N and Bi—O bond lengths. Although the atoms Bi1, N1, O11, N2, O21 and O31 are not exactly coplanar, the sum of the corresponding angles is close to 360°, 359.80 (9)° (N1—Bi1—O11 = 64.98 (9)°, O11—Bi1—N2 = 74.25 (9)°, N2—Bi1—O21 = 67.72 (9)°, O21—Bi1—O31 = 77.37 (9)°, O31—Bi1—N1 = 75.49 (9)°). The C—Bi—O and C—Bi—N angles deviate from 90° (83.65–92.00°), contributing to the distortion of the pentagonal pyramidal coordination around the BiIII atom (Figure 2). Similar to other structurally characterized arylbismuth(III) compounds, the coordination sphere of BiIII is hemidirected (Stavila et al., 2007, 2009), (Stavila & Dikarev, 2009), suggesting that a stereochemically active
is present.Generally, secondary bonding interactions are rather common for monoaryl-bismuth(III) complexes. Thus, intermolecular secondary bonding interactions have been found in a number of aryl-bismuth diketonates (Stavila & Dikarev, 2009) and carboxylates (Stavila et al., 2007). In (I), the oxygen atom of one of the hydroxyl groups, O23, is involved in a weak secondary bond (Bi1···O23 = 3.485 (3) Å with an adjacent BiIII complex (Figure 3). The complex also displays intra- and intermolecular hydrogen bonds between the OH groups and oxygen atoms of the carboxylate groups (O13—H13A···O12, O13···O12 = 2.541 (5) Å; O23—H23A···O22, O23···O22 = 2.555 (5) Å; O23—H23A···O13i, O23···O13i = 2.917 (6) Å, (i) x + 1, y, z + 1).
Structures containing aryl bismuth(III) complexes with O or O/N donors typically display pentagonal pyramidal geometries and are comparatively rare (Andrews et al., 2006; Stavila & Dikarev, 2009; Stavila et al., 2007; Yu et al., 2004). In the same way, structures of bismuth(III) complexes with chelating picolinate ligands are uncommon (Callens et al., 2008).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

The title compound, (I), was obtained from the solvent-free reaction of BiPh3 and 3-hydroxypicolinic acid (3-hpicH) with subsequent recrystallization from dimethylformamide (dmf) (see Experimental). Single-crystals suitable for X-Ray crystallography were obtained at room temperature from the concentrated dmf solution. The structure determination of (I) revealed a mononuclear compound, in which the BiIII atoms are hexa-coordinated in a distorted pentagonal pyramidal geometry with two N and two O atoms of N,O-chelating 3-hpic ligands and one dmf O donor in the equatorial plane (Figure 1). The axial position of the pentagonal pyramid is occupied by a carbon atom of the aryl group (Bi1—C41 = 2.245 (4) Å). Both picolinate ligands are monodeprotonated and display N,O-chelation through the pyridine N and carboxylate O atoms. There is an important asymmetry in the 3-hpic coordination to BiIII (Bi1—N1 = 2.660 (3) Å, Bi1—O11 = 2.348 (3) Å; Bi1—N2 = 2.488 (3) Å, Bi1—O21 = 2.382 (3) Å). The O atom of the coordinated dmf molecule (Bi1—O31 = 2.534 (3) Å) completes the equatorial plane of the pyramid.
There is a relatively large variation in the equatorial angles of the pyramid (64.97 – 77.37°) due to the difference in Bi—N and Bi—O bond lengths. Although the atoms Bi1, N1, O11, N2, O21 and O31 are not exactly coplanar, the sum of the corresponding angles is close to 360°, 359.80 (9)° (N1—Bi1—O11 = 64.98 (9)°, O11—Bi1—N2 = 74.25 (9)°, N2—Bi1—O21 = 67.72 (9)°, O21—Bi1—O31 = 77.37 (9)°, O31—Bi1—N1 = 75.49 (9)°). The C—Bi—O and C—Bi—N angles deviate from 90° (83.65–92.00°), contributing to the distortion of the pentagonal pyramidal coordination around the BiIII atom (Figure 2). Similar to other structurally characterized arylbismuth(III) compounds, the coordination sphere of BiIII is hemidirected (Stavila et al., 2007, 2009), (Stavila & Dikarev, 2009), suggesting that a stereochemically active lone electron pair is present.
Generally, secondary bonding interactions are rather common for monoaryl-bismuth(III) complexes. Thus, intermolecular secondary bonding interactions have been found in a number of aryl-bismuth diketonates (Stavila & Dikarev, 2009) and carboxylates (Stavila et al., 2007). In (I), the oxygen atom of one of the hydroxyl groups, O23, is involved in a weak secondary bond (Bi1···O23 = 3.485 (3) Å with an adjacent BiIII complex (Figure 3). The complex also displays intra- and intermolecular hydrogen bonds between the OH groups and oxygen atoms of the carboxylate groups (O13—H13A···O12, O13···O12 = 2.541 (5) Å; O23—H23A···O22, O23···O22 = 2.555 (5) Å; O23—H23A···O13i, O23···O13i = 2.917 (6) Å, (i) x + 1, y, z + 1).
Structures containing aryl bismuth(III) complexes with O or O/N donors typically display pentagonal pyramidal geometries and are comparatively rare (Andrews et al., 2006; Stavila & Dikarev, 2009; Stavila et al., 2007; Yu et al., 2004). In the same way, structures of bismuth(III) complexes with chelating picolinate ligands are uncommon (Callens et al., 2008).
