Source of material

All chemicals and solvents purchased were of reagent grade and used without further purification. Neodymium(III) nitrate hexahydrate (0.438 g, 1 mmol), 3,4,5,6-tetrachlorophthalic acid (0.608 g, 2 mmol) and 4,4′-bipyridine (0.312 g, 2 mmol) were mixed in ethanol (80 ml). The pH value of the mixture was adjusted to about 6.5 by the potassium hydroxide solution, and then stirred at 80°C for 8 hours. After filtration, the resulting solution was stood at room temperature for several days. Crystals suitable for X-ray analysis were collected by filtration.

Experimental details

All the H atoms of carbon were treated as riding-model, with C—H = 0.93–0.98 Å, and their Uiso = 1.2Ueq(carrier atom). Water H atoms except O4W were located in a difference Fourier map and refined with O—H = 0.85(1) Å and Uiso(H) = 1.5Ueq(O). H atoms were not added to water O4W due to its disorder (occupancy factor: 0.5).

Discussion

As a versatile benzendicarboxylate ligand, the tetrachlorophthalate ligand was rarely used to construct complex. By now, there are few of published reports concerning metal complexes with 3,4,5,6-tetrachlorophthalate (tcph), which may play the role of bridging ligand in transition metal complexes [1–6] and terminal ligand in rare earth metal complexes [7–11]. All the reported rare earth metal complexes have a mononuclear structure and contain the Htcph or tcph2− ligand in terminal coordinate style. Whereas, this article presents a novel mixed neodymium and potassium complex with a two-dimentional network structure, showing the tcph2− ligand in the polydentate bridging mode.

The title compound contains two kinds of metal ion, Nd3+ and K+ ions. The asymmetric unit contains a NdK(tcph)2 moiety and 5.5 water ligands. Nd(III) ion is eight-coordinated with five oxygen atoms from three tcph2− ligands and three oxygen atoms from three coordination waters. K(I) is also eight-coordinated with four oxygen atoms from two tcph2− ligands and four oxygen atoms from four coordination waters. Ligand tcph2− has two kinds of coordination style in the title complex. Two tcph2− ligands construct two K(I) and two Nd(III) ions into a [Nd2K2(tcph)2]4− tetranuclear unit in a hexadentate chelating-bridging mode, and the other two tcph2− ligands both bridge the two neighboring Nd(III) ions of the tetranuclear unit in tridentate bridging style into an infinite chain along the b axis. The adjacent infinite chains are further connected into a 2D network in the ab plane by the bridging water O4W between the K(I) ions. The 4,4′-bipyridine molecule connects the 2D networks into a three-dimentional supramolecule via N–H⋯O hydrogen bonds between the coordination waters O2W, O5W and N2, N1 of 4,4′-bipyridine, respectively. Moreover, there are a lot of hydrogen bonds between the coordination waters, carboxylate O atoms and coordination waters in the structure.
