2O2:O5] dihydrate]
In the title hydrated coordination polymer, {[Zn(C6H2O5)(C10H8N2)(H2O)]·2H2O}n, an infinite [1-10] chain is formed by the linking of [Zn(C10H8N2)(H2O)]2+ entities by bridging, monodentate furan-2,5-dicarboxylate dianionic linkers. The Zn2+ coordination geometry is a trigonal bipyramid, with one N atom (from 2,2'-bipyridine) and one O atom (from the bridging dianion) in the axial positions. For each ZnII atom, the dihedral angle between the furan ring of its coordinated bridging ligand and its coordinated bipyridine ring system is 87.19 (8)°. O-H
O hydrogen bonds involving both the coordinated and uncoordinated water molecules generate a layer motif parallel to (001).
In a typically synthesized route of (I), furan-2,5-dicarboxyl acid (0.0156 g,
0.10 mmol), Zn(NO3)2.6H2O (0.0300 g, 0.10 mmol), and 2,2'-bipyridine
(0.0156, 0.10 mmol) and NaOH (0.004, 0.10 mmol) were dissolved in water (5 ml,
278 mmol) under stirring. The mixture with molar ratio of 1
(furan-2,5-dicarboxyl acid): 1 (Zn(NO3)2.6H2O): 1 (2,2'-bipyridine): 1
NaOH: 2780 H2O was layed under room temperature for 5 days. The colorless
block product was collected as a single phase.
Water H atoms were located in a difference Fourier map and refined with O—H =
0.87 (2) Å and Uiso(H) = 1.2Ueq(O). The carbon H-atoms were placed
in calculated positions (C—H (furan and pyridine ring) = 0.93 Å) and were
included in the refinement in the riding-model approximation, with
Uiso(H) = 1.2Ueq(C).

Special details top
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. |

As the analogous structure of BDC (benzene-1,4-dicarboxyl acid), FDA (furan-2,5-dicarboxyl acid) attracts attentions owing to the bond angle of two carboxyl groups about 126° Recently, we utilized furan-2,5-dicarboxyl acid as the ligand to construct coordination polymers (Li, et al., 2012). As an extension of this work, a chainlike compound, [Zn(H2O)(C10H8N2)(C6H2O5)].2H2O (I), is now determined.
The asymmetric unit of (I) is consisted of one Zn(II) cation, one furan-2,5-dicarboxylate anion, one 2,2'-bipyridine and three waters involving in one coordinated waters and two structural water (Fig.1). Zn cation is coordinated by two N atoms of 2,2'-bipyridine, one water O atoms and two carboxylate O atoms, exhibiting a triangle bipyramid geometry (Table 1) with one O atoms of furan-2,5-dicarboxylate and one nitrogen atom of 2,2'-bipyridine in the axial positions. The adjacent Zn cations are connected by the furan-2,5-dicarboxylate to infinite chain (Fig.2). Owater—H···O hydrogen bonds (Table 2) help to consolidate the structure.
