Zn(CH3COO)2.2H2O (0.110 g, 0.5 mmol), H2bpea (0.133 g, 0.5 mmol) and L1 (0.118 g, 0.5 mmol) were dissolved in a mixed solution of DMF (9 ml) and distilled water (5 ml). The resulting mixture was stirred for about 1 h at room temperature, sealed in a 23 ml Teflon-lined stainless steel autoclave, and heated at 398 K for 8 d under autogenous pressure. The reaction system was gradually cooled to room temperature at a rate of 5 K h-1. Pale yellow crystals of (I) suitable for single-crystal X-ray diffraction analysis were collected from the final reaction system by filtration, washed several times with DMF, and dried in air at ambient temperature (yield 55% based on ZnII).
Compound (II) was prepared in the same way as (I), using L2 as an N-donor chelating ligand. Pale yellow crystals were obtained (yield 47% based on ZnII).
For (I) and (II), all H atoms were positioned geometrically (C—H = 0.93 Å) and refined as riding, with Uiso(H)=1.2Ueq(carrier). The water H atoms were located in a difference Fourier, and were refined with distance restraints of O—H 0.85±0.01 and H···H 1.39±0.01 Å. Their temperature factors were freely refined.
The DMF molecule of (II) is disordered about a centre of inversion. The C—O length was restrained to 1.25±0.01 Å, the N–C(carbonyl) length was restrained to 1.35±0.01 Å and the other two N—C lengths to 1.45±0.01 Å. The atoms were restrained to lie on a plane. The anisotropic temperature factors were restrained to be nearly isotropic.

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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. |

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. |

The rational design and synthesis of novel discrete and polymeric metal–organic compounds have attracted increasing interest due to their fascinating structural topologies and their potential applications as functional materials in catalysis, separation and nonlinear optics (Batten & Robson, 1998; Carlucci et al., 2003; Eddaoudi et al., 2001; Ockwig et al., 2005). Considerable progress has been made in controlling the synthesis of networks with interesting topologies (Yang et al., 2008; Batten, 2001) by varying the factors that affect framework formation; however, it is not possible to predict with complete accuracy the exact structure of the resulting framework. It is therefore important to gain a full understanding of the roles of the factors that influence the formation of metal–organic coordination frameworks (Hagrman et al., 1999).
In general, there are several factors that can influence the network structures of their compounds, such as the coordination environments of metal nodes, and the structural characteristics of the ligands, solvents, templates and counterions (Hu et al., 2006). Among these, the selection of an N-containing ligand is extremely important because, by changing the structures of the N-containing ligands, it is possible to adjust the topologies of coordination frameworks, even for structures containing the same spacer ligand and metal cation (Wang et al., 2005). So far, although the effect of an N-containing ligand on the structures of complexes has been studied, few systematic investigations on the influence of N-containing ligands on their complex structures have been carried out (Tong et al., 2000; Zheng et al., 2001). In particular, the influence of N-containing chelating ligands on network construction through π–π interactions has rarely been documented (Yang, Ma et al., 2007). To the best of our knowlege, the influence of different 1,10-phenanthroline derivatives on the structures of metal–dicarboxylates has not been studied to date (Yang, Li et al., 2007). In this work, we chose biphenylethene-4,4'-dicarboxylic acid (H2bpea) as the bridging ligand, dipyrido[3,2-a:2',3'-c]-phenazine (L1) and pyrazino[2,3-f][1,10]phenanthroline (L2) as the different N-donor chelating ligands, yielding a centrosymmetric dinuclear complex [Zn2(L1)2(bpea)(H2O)2].2H2O, (I), and a chain [Zn(L2)(bpea)(H2O)].0.5DMF, (II) (DMF = dimethylformamide).
Selected bond lengths and angles for (I) are given in Table 1. In compound (I), the coordination geometry of each ZnII centre is distorted octahedral, with two N atoms from one L1, and four O atoms from one bis-chelating acetate anion, one bridging bpea and one water molecule (Fig. 1). The adjacent ZnII atoms are bridged by one bpea ligand to form a dinuclear complex with a long Zn···Zn distance of 17.405 (3) Å (Fig. 1). The dinuclear species is centrosymmetric, with a crystallographic inversion centre midway between the two ZnII atoms. Notably, the L1 ligands are arranged in a parallel fashion at both sides of a dinuclear species, leading to a structure suitable for aromatic intercalation. Two types of π–π interactions between neighbouring dinuclear species have been found: one is between the L1 ligands [centroid-to-centroid distance of 3.555 (2) Å, vertical face-to-face distance of 3.483 (1) Å, and dihedral angle of 2.212 (1)°], and the second is between the L1 and bpea anion [centroid-to-centroid distance of 4.027 (2) Å, vertical face-to-face distance of 3.505 (1) Å, and dihedral angle of 2.720 (2)°] (Fig. 2). In these modes, a two-dimensional supramolecular layer is formed (Fig. 2). The layers are further linked by O—H···O and O—H···N hydrogen bonds, generating a three-dimensional supramolecular network (Table 2).
It is noteworthy that the structure of (I) is different from that of the related dinuclear structure [Pb(L1)(adip)]2 (adip is adipate; Yang, Ma et al., 2007), in which the two adip ligands link the two PbII centres to give a dinuclear species. A two-dimensional supramolecular layer is formed through only one type of π–π interaction between L1 ligands of neighbouring dinuclear species. The structure of (I) is also entirely different from that of the related polymer [Mn2(L1)(dpdc)2]n (dpdc is the 2,2'-diphenyldicarboxylate dianion; Che et al., 2008). In that structure, four MnII atoms are bridged by the carboxylate groups of the dpdc ligands to form an unusual tetranuclear MnII cluster; the clusters are further connected together by the aromatic backbone of the dicarboxylate ligands, forming a one-dimensional chain structure along the b axis.
To investigate the influence of N-donor chelating ligands on the complex frameworks, a relatively small ligand L2 was used under the same reaction conditions as for (I), and a structurally different coordination polymer [Zn(L2)(bpea)(H2O)].0.5DMF, (II), was obtained from the reaction system. As shown in Fig. 3, each ZnII atom is square-pyramidally coordinated by two N atoms from one L2 ligand, three O atoms from two different bpea ligands and one water molecule. The average Zn—O and Zn—N distances in (II) are comparable with those observed for (I) (Table 3). The two bpea dianions are situated across inversion centres. As depicted in Fig. 4, the bpea dianions bridge two neighbouring ZnII centres, giving a one-dimensional chain structure in the ab plane. Clearly, the N-containing chelating ligand L2 plays an important role in the formation of the chain structure. Two N atoms from the secondary L2 ligand occupy two coordination positions of the ZnII atom, while the remaining coordination positions are available for bpea ligands, allowing the formation of the chain structure. As in (I), two types of π–π interactions between neighbouring chains have been found: one is between the L2 ligands [centroid-to-centroid distance of 3.705 (1) Å, vertical face-to-face distance of 3.430 (3) Å, and dihedral angle of 0.000 (1)°], and the second is between L2 and bpea anions [centroid-to-centroid distance of 3.632 (1) Å, vertical face-to-face distance of 3.424 (1) Å, and dihedral angle of 5.150 (7)°] (Fig. 5). In these modes, a three-dimensional supramolecular structure is formed (Fig. 5). The O—H···O hydrogen bonds further consolidated the structure of (II) (Table 4).
It is noteworthy that the structure of (II) is entirely different from that of the related structure [Cd2(L2)2(1,4-ndc)2] (1,4-ndc is 1,4-naphthalenedicarboxylate; Qiao et al., 2008), where the tetranuclear cadmium carboxylate clusters are connected together by the aromatic backbone of the dicarboxylate ligands, forming a three-dimensional α-polonium net.
In summary, by varying the N-containing chelating ligand under the same synthesis conditions, two structurally different ZnII complexes are obtained. In contrast to L2, the bulky phenyl groups in the backbone significantly increase the steric hindrance of the L1 ligand, leading to the formation of (I) and (II) with quite different structures. Therefore, the structures of the N-containing chelating ligands are the dominant factor determining the final supramolecular structures of the two compounds.
