Crystals where grown by slow evaporation at ambient conditions of a methanol solution of 3-pyridinepropionic acid.
The C-bound H atoms were geometrically placed (C—H bond lengths of 0.95 (aromatic CH) and 0.99 (CH2) Å) and refined as riding with Uiso(H) = 1.2Ueq(C). The O-bound H atom were geometrically placed and refined as riding with Uiso(H) = 1.5Ueq(O).
The molecule 3-pyridinepropionic acid (I) has been used as a ligand to make coordination polymers using Ag, Cu and Zn (Wang et al., 2006). The
of the molecule itself has not been reported. The solid state packing involves forming chains of molecules, generated by hydrogen bonding interactions from the carboxylic acid H to the lone pair of the pyridine N atom. The chain, described using graph set notation (Bernstein et al., 1995) as C(8), is generated by the twofold screw axis inherent in the spacegroup P21/c, and runs along the crystallographic b axis (See Fig 2). Adjacent chains are stabilized by two C—H···O hydrogen bonds (See Table 1).For use of the title compound in coordination polymers, see: Wang et al. (2006). For graph-set nomenclature of hydrogen bonds, see: Bernstein et al. (1995).

Experimental. Numerical integration absorption corrections based on indexed crystal faces were applied using the XPREP routine (Bruker, 1999) |
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. |
