Abstract top

In the title compound, {(C10H11N3)[Zn3(C8H4O4)4]·2H2O}n, divalent Zn atoms are linked into trinuclear units featuring tetrahedral, octahedral and distorted tetrahedral, octahedral and square-pyramidal coordination geometries. These trinuclear units are connected by isopthalate dianions into [Zn3(isophthalate)4]n2n- anionic layers, which aggregate into the three-dimensional structure via hydrogen-bonding pathways mediated by doubly protonated 4,4'-iminodipyridinium cations and water molecules of crystallization. One solvent water molecule was found to be disordered over two positions, each with a 50% site-occupancy factor.

Comment top

Recently, we reported Co and Ni phthalate 1-D coordination polymers containing the hydrogen-bonding capable, dipodal tethering ligand 4,4'-dipyridylamine (dpa) (Braverman et al., 2007). In an attempt to extend this chemistry into a zinc isophthalate coordination polymer system, colourless crystals of the title compound, (I), were obtained.

The asymmetric unit of (I) contains three divalent Zn atoms, four crystallographically distinct doubly deprotonated isophthalate dianions, one doubly protonated H2dpa2+ dication and two water molecules of crystallization, one of which is disordered equally over two positions, Fig. 1. The Zn atoms are linked into a trinuclear cluster by bridging carboxylate groups and O atoms from the isophthalate ions, in which Zn2, Zn1 and Zn3 adopt tetrahedral, octahedral and distorted square pyramidal coordination geometries, respectively.

Each trinuclear unit is linked to two others along the a-axis by two sets of two exotetradentate isophthalate dianions, which bridge two Zn atoms through a carboxylate bridge and two other Zn atoms through a single O atom connection. The trinuclear units also conjoin along the b-axis. Here, each trinuclear unit again connects to two others, via two sets of two crystallographically distinct exotridentate isophthalate dianions. One of these adopts a bis-bridging/chelating binding mode, while the other possesses a bis-bridging/monodentate binding mode. The resulting [Zn3(isophthalate)4]n2n- anionic layers contain incipient voids occupied by H2dpa2+ dications and water molecules of crystallization, Fig. 2. These layers are arranged parallel to the bc-plane. Abutting [Zn3(isophthalate)4]n2n- layers aggregate into the 3-D structure through hydrogen-bonding patterns between the protonated pyridyl-N atoms of the H2dpa2+ dications, carboxylate-O atoms and water molecules of crystallization, Table 1 and Fig. 3.

Experimental top

All chemicals were obtained commercially with the exception of 4,4'-dipyridylamine which was prepared according to a literature procedure (Zapf et al., 1998). Zinc chloride dihydrate (64 mg, 0.37 mmol), isophthalic acid (62 mg, 0.37 mmol) and 4,4'-dipyridylamine (127 mg, 0.74 mmol) were placed into H2O (10 ml ) in a 23 ml Teflon-lined Parr acid digestion bomb. The bomb was heated at 393 K for 72 h and was then allowed to cool to room temperature. Colourless crystals of (I) were obtained along with a white powdery solid.

Refinement top

All H atoms bound to C atoms were placed in calculated positions, with C—H = 0.93 Å and refined in riding mode with Uiso = 1.2Ueq(C). The H atoms bound to O atoms were found via a Fourier difference map, restrained at fixed positions or with O—H = 0.85 Å, and refined with Uiso=1.2Ueq(O). The H atoms bound to N atoms were found via a Fourier difference map, restrained with N—H = 0.91 Å (for pyridyl N atoms) or with N—H = 0.89 Å (for the amine N atom), and refined with Uiso=1.2Ueq(N). See Table 1 for O-H and N-H distances. One water molecule was found to be disorderd over two sites, each with equal weight; the H atoms could not be located.

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.
