3O2,N,O6)dizincate(II) dihydrateThe title compound, (CH6N3)[Zn2(C7H3NO5)2(C7H4NO5)(H2O)]·2H2O, has an anionic binuclear complex of ZnII balanced with a guanidinium cation. There are two uncoordinated water molecules in the structure. The asymmetric unit of the compound has two different coordination types (the coordination of Zn1 is distorted trigonal-bipyramidal, while that of Zn2 is distorted octahedral) of ZnII in the crystal structure that are bridged to each other via one hypydc2- group (hypydcH2 is 4-hydroxypyridine-2,6-dicarboxylic acid). A variety of intermolecular O-H
O, N-H
O and C-H
O hydrogen bonds involving water molecules, cations and anions, and also a weak

interaction [3.798 (1) Å], are responsible for extending the structure into a three-dimensional network.
An aqueous solution of 200 mg guanidine hydrochloride (2 mmol) with 80 mg sodium hydroxide (2 mmol) was prepared. After stirring the obtained suspension, an aqueous solution of 291 mg ZnSO4.7H2O (1 mmol) and 360 mg 4-hydroxypyridine-2,6-dicarboxylic acid (2 mmol) was added to it. The mixture with the volume of 50 ml was heated and boiled for 2 h. Colorless crystals were obtained by slow cooling during three days.
The positions of hydrogen atoms on amino and hydroxo groups and water molecules were located from the difference Fourier syntheses and normalized to 0.88, 0.84 and 0.85%A distances, respectively. All hydrogen atom positions were refined in isotropic approximation in riding model with with the Uiso(H) parameters equal to 1.2(N) for amino, 1.2Ueq(O) for hydroxo groups, to 1.2Ueq(C) for all carbon atoms and to 1.5Ueq(O) for water molecules where Ueq(C) and Ueq(O) are the equivalent thermal parameters of the atoms to which corresponding H atoms are bonded.

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. |

After the synthesis of proton transfer ion pairs with the formulae of (GH)(hypydcH) (Moghimi, Aghabozorg, Soleimannejad et al., 2005) and (GH)(hypydcH).H2O (Moghimi, Aghabozorg, Sheshmani et al., 2005), the first metallic compound related to them formulated as (GH)2[Ni(hypydc)2] .2H2O was synthesized (Aghabozorg, Motyeian et al., 2008). Slightly different, the title compound is another metallic compound related to the mentioned ion pairs.
The molecular structure of the compound is shown in Fig. 1. A s it can be observed, the anionic complex involves two ZnII atoms with different coordination modes including penta and hexa-coordination. One ZnII is coordinated to two (hypydc)2- groups, one of which is bridged to the second ZnII which is also coordinated to an (hypydcH)- group and a water molecule. The coordination polyhedron around Zn1 is a distorted trigonal bipyramid, while that of Zn2 is a distorted octahedron (Fig. 2). It is notable that the –COOH of the (hypydcH)-group is coordinated to Zn1 via its carbonyl O3 atom, while the –COO- group is coordinated to Zn1 through its O1 atom, as usual. This is shown by essentially different C7–O3 (1.229 (2) Å) and C6–O1 (1.273 (2) Å) bond lengths. Moreover, (GH)+ as counter ion and two uncoordinated water molecules are incorporated in the structure. Investigating the angles of (GH)+ shows that the sum of all three angles around C22 (120.63 (19), 120.05 (19) and 119.30 (19)°) confirms the coplanarity of the three bonds. In addition, since the three bonds of (GH)+ are almost the same (N4–C22, 1.325 (3); N5–C22, 1.328 (3) and N6–C22, 1.327 (3) Å), it can be concluded that the positive charge is delocalized on the counter ion.
By comparison, the bond length of Zn1–O1 (2.0955 (14) Å) is obviously shorter than Zn1–O3 (2.4440 (15) Å). This is due to that O3 is of unprotonated –COOH group, but O1 is belonged to the deprotonated carboxylate group. Thus, Zn1–O3 is longer than the Zn1–O1 bond. This resembles to (pydaH)[Zn(pydc)(pydcH)]. 3H2O (pyda: pyridine-2,6-diamine, pydcH2: pyridine-2,6-dicarboxylic acid) complex in which the carbonyl oxygen atom of –COOH group forms a longer bond to metallic center (Ranjbar et al., 2002). Also, the length of Zn2–O13 is longer than Zn2–O11, i.e. the bridge O13 atom lies further to Zn2, this is similar to polymeric (GH)[Bi(pydc)(H2O)] complex in which the bridge oxygen atom forms a longer bond to BiIII atom (Sharif et al., 2007). Moreover, the lengths of Zn1–O13 (1.9541 (14) Å) and Zn2–O13 (2.3857 (14) Å) are significantly different. As the O13–Zn2–O8–C14 (-83.49 (14)°) and O13–Zn2–O6–C13 (86.01 (14)°) torsion angles and O6–Zn2–O11 (90.99 (6)°) and O8–Zn2–O13 (86.07 (5)°) bond angles show, the two (hypydc)2- rings coordinated to Zn2 are almost perpendicular.
The bond angles of Zn2 to four oxygen atoms of carboxylate groups show that they are oriented on a flattened tetrahedral arrangement around the metallic center (Table 1).
As shown in Fig. 3, there are plenty of hydrogen bonds of type O–H···O and N–H···O ranging from 2.586 (2) to 3.344 (2) Å, and C–H···O bonds with 2.993 (2) and 3.046 (3) Å lengths between the fragments (Table 2). Also, there is a weak π-π interaction with distance of 3.798 (1) Å between the aromatic rings (Fig. 4). The crystal packing of the compoud is shown in Fig. 5. A s illustrated in Fig. 6, there are a type of channels produced by aromatic rings of the structure with the distance of ~3.3 Å.
