Abstract top

The title compound, (C4H12N2)3[Nd(C7H3NO4)3]2·15.33H2O or (pipzH2)3[Nd(pydc)3]2·15.33H2O (in which pipz is piperazine and pydcH2 is pyridine-2,6-dicarboxylic acid), was synthesized by the reaction of NdCl3·6H2O with the proton-transfer compound (pipzH2)(pydc) in aqueous solution. The nine donor atoms of the three pydc2- ligands form a distorted tricapped trigonal-prismatic arrangement around the NdIII center. Considerable C-O...[pi] stacking interactions between CO groups of carboxylate fragments and aromatic rings of pydc2- with distances of 3.135 (5)-3.255 (5) Å are observed. In the crystal structure, a wide range of hydrogen-bonding [of the types O-H...O, N-H...O and C-H...O, with D...A distances ranging from 2.608 (10) to 3.278 (7) Å], ion-pairing and C-O...[pi] stacking interactions connect the various components into a supramolecular structure. There is a high degree of solvent disorder in the structure; the occupancies of five water molecules refined to 0.6, 0.5, 0.4, 0.25 and 0.25.

Comment top

Recently, we have defined a plan to prepare water soluble proton transfer compounds as novel self assembled systems that can function as suitable ligands in the synthesis of metal complexes. In this regard, we have reported cases in which proton transfers from pyridine-2,6-dicarboxylic acid, pydcH2, and benzene-1,2,4,5-tetracarboxylicacid, btcH4, to propane-1,3-diamine (pn) and 1,10-phenanthroline, (phen), resulted in the formation of novel self-assembled (pnH2)(pydc).(pydcH2).2.5H2O, (pnH2)2(btc).2H2O and (phenH)4(btcH3)2(btcH2) systems, respectively. The resulting compounds with some remaining sites as electron donors can coordinate to metallic ions (Aghabozorg, Attar Gharamaleki, Ghadermazi et al., 2007; Aghabozorg, Attar Gharamaleki, Ghasemikhah et al., 2007; Aghabozorg, Daneshvar et al., 2007, and references therein).

Here, we report on the synthesis and X-ray crystal structure of the title compound. The molecular structure of the title compound (I) is presented in Fig. 1. Selected bond lengths and angles of the structure (I) are presented in Table 1. Hydrogen bond lengths are given separately in Table 2.

In structure (I), NdIII is coordinated by three (pydc)2– groups as tridentate ligands and a nine coordinated complex results. For balancing the anionic complex, protonated piperazine, (pipzH2)2+, exists. The sum of bond angles, N1—Nd1—N2, N1—Nd1—N3 and N2—Nd1—N3 equals to 359.60 (12)° and indicates that Nd1 is located in the center of N1N2N3 plane. The three O atoms O1, O5 and O9 form a triangle and the other three, O3, O7 and O11 form another triangle around the NdIII. So a distorted tricapped prism polyhedron is proposed.

Moreover, there are uncoordinated water molecules which are involved in the formation of hydrogen bonds. These water molecules form six members cyclic rings with acyclic side chains water clusters (Fig. 2).

A noticeable feature of the title compound is the presence of C—O···π stacking interactions between CO group of carboxylates with aromatic rings of (pydc)2– units. The C—O···π distances (measured to the center of phenyl ring) are 3.134 (5) Å for C6—O2···Cg1 (1 + x, y, z), 3.245 (5) for C21—O10···Cg2 (x, y, z) and 3.255 (5) Å for C13—O6···Cg3, [Cg1, Cg2 and Cg3 are the centroids of N1/C1—C5, N2/C8—C12 and N3/C15—C19 rings, respectively] (Fig. 3).

In the crystal structure, a wide range of non-covalent interactions consisting of hydrogen bonding (of the type O—H···O, N—H···O and C—H···O with D···A ranging from 2.608 (10) to 3.278 (7) Å, ion pairing and C—O···π stacking connect the various components into a supramolecular structure (Table 2, Fig. 4).

Experimental top

The proton transfer compound of (pipzH2)(pydc) was prepared according to our reported procedure (Aghabozorg et al., 2006). A solution of NdCl3.6H2O (320 mg, 1 mmol) in water (15 ml) was added to a solution of a solution of proton transfer compound (pipzH2)(pydc) (500 mg, 2 mmol) in water (10 ml) in a 1:2 molar ratio. Colorless crystals of (I) suitable for X-ray characterization were obtained after a few days at room temperature.

Refinement top

There is a high positive residual density of 4.81 e Å-3 at 0.63 Å near the Nd1 center due to considerable absorption effects which could not be completely corrected.

There is a high solvent disorder in the structure. Occupancies of water molecules O7W, O8W, O9W, O10W and O11W were found out by refinement of occupation factors for this molecules as free variables and are equal to 0.6, 1/2, 0.4, 0.25 and 1/4, respectively.

The hydrogen atoms positions on carbon atoms were found geometrically. The hydrogen atoms on ordered water molecules and nitrogen atoms were found from difference Fourier maps, and for disordered water molecules were not located. All hydrogen atoms were treated in riding model with the Uiso(H) parameters equal to 1.2 Ueq(C), 1.2 Ueq(N) and 1.5 Ueq(O) where Ueq(C), Ueq(N) 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.
