-4,4'-(propane-1,3-diyldioxy)dibenzoato]
In the title compound, [Co(C17H14O6)(C12H8N2)(H2O)]n, the CoII atom is coordinated by a monodentate 4,4'-(propane-1,3-diyldioxy)dibenzoate (cpp) dianion, a water molecule and a chelating 1,10-phenanthroline (phen) ligand. A symmetry-generated cpp ligand completes the CoN2O3 trigonal-bipyramidal geometry for the metal ion, with the N atoms occupying both equatorial and axial sites. The bridging cpp ligands form chains propagating in [110] and O-H
O hydrogen bonds consolidate the packing.
The followinf quantities were mixed:
(23 mg, 0.1 mmol)) Co(NO3)2 of water solution (5 ml) and
H2CP (26 mg, 0.1 mmol), phen (0.19 mg, 0.1 mmol) and
NaOH (3.8 mg, 0.09 mmol), CH3CN (5 ml) and heated to
at 428 K for 60 h in a pressurized reactor. Slow evaporation of this
solution resulted in the formation of some pink blocks
of (I).
All H atoms attached to C atoms were fixed geometrically and treated
as riding with C—H = 0.93 Å (aromatic)
with Uiso(H) = 1.2Ueq(C). H atoms of water molecule were
located in difference Fourier maps and included in the subsequent refinement
using restraints (O-H = 0.84 (2)Å and H···H = 1.38 (2)Å) with
Uiso(H) = 1.5Ueq(O).
The highest residual difference electron-density peak is 1.50Å
from N3.

Special details top
Geometry. All esds (except the esd in the dihedral angle between two l.s. planes)
are estimated using the full covariance matrix. The cell esds are taken
into account individually in the estimation of esds in distances, angles
and torsion angles; correlations between esds in cell parameters are only
used when they are defined by crystal symmetry. An approximate (isotropic)
treatment of cell esds is used for estimating esds 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 > 2sigma(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. |

Design of effective ligands and the proper choice of metal centers are the keys to design and construct novel metal-organic frameworks (Kitagawa et al., 2004; Schokecht & Kempe, 2004). Polycarboxylate ligands have received considerable attention, owing to the variety of their coordination modes and structural features. 4,4'-(propane-1,3-diyldioxy)dibenzoic acid (H2cpp) is a potential multi-dentate ligand with a versatile coordination mode, which has been used in self-asssembled porous coordination synthesis (Liu et al., 2009).
The title compound, (I), was constructed by two kinds of bridging and chelating ligands under mild condition, H2cpp and phen which were self-assembled to a one-dimensional neutral metal-organic compound. In this paper, the crystal structure of (I) is presented.
As illustrated in Fig. 1, CoII adopts a trigonal bispyramidal geometry, generated by three O atoms from two adjacent monodenated-chelating carboxylate groups and one coordinated water molecule, and two N atoms from one chelating phen ligand. The three atoms (O1, O1W and N3) in the basical plane around the Co atom, while the other two atoms (O6 and N4) locate at apical positions. The twist angle of two rings of cpp ligand is 96.8 (5)°.
The neighboring Co atoms are linked by cp ligands forming a one-dimensional chain running along a axis (Fig. 2). These chains are decorated with phen ligands alternating on two sides, which is similar with some complexes (Chen & Liu, 2002) There are no π-π interactions between rings of phen ligands due to its transplacement arrangement.
In the crystal structure, strong intermolecular O-H···O hydrogen bonds (Table 1) link the molecules into a 2D network, in which they may be effective in the stabilization of the structure.
