A golden block-like crystal of 1 with dimensions 0.408mm0.192mm0.117mm was selected on a Bruker P4 diffractometer with graphite-monochromated Mo-Ka radiation (¼0.71073A ˚ ) at 292K using the –2 scan technique. The data were corrected for Lp and absorption effects. The crystal structure was solved using direct methods with the SHELXS-97 program [15]. Subsequent difference Fourier syntheses enabled all heavier atoms to be located. All hydrogen atoms were located from the successive difference Fourier syntheses. The non-hydrogen atoms were finally refined with anisotropic displacement parameters by full-matrix least-squares techniques [16]. The hydrogen atom positions were fixed geometrically at calculated distances and allowed to ride on the parent carbon atoms. The same manipulation for 2 was conducted as described above. Detailed information about the crystal data and structure determination for both compounds are summarized in table 1.Their selected interatomic distances and bond angles are given in table 2. CCDC NO.: 633035 (1), 633034 (2). 3. Results and discussion The IR spectra of both compounds display three strong absorptions at 1588(s), 1484(s), 1445(vs) cm1 for 1 and 1589(s), 1480(s), 1441(vs), cm1 for 2, due to the characteristic as (COO) and s (COO) stretching modes of carboxylate groups [17]. There are broad bands around 3438 cm1 observed in 1 and 2, suggesting water persists in both compounds. The one-dimensional structure of 1 was revealed by X-ray single-crystal structure analysis. Crystallographic data of 1 (as shown in table 1) indicates that [Mg(L) (4H2O)]n 1 belongs to a monoclinic system, space group P2(1)/c and Z¼4. Figure 1 presents the local coordination environment around magnesium as six-coordinate with two monodentate carboxylate groups of different olsalazine ligands and four water molecules. The coordination geometry can be best described as a distorted octahedron with a plane constructed by O(3A), O1W, O2W and O3W and apical sites occupied by O(4) and O4W with angle (O(4)–Mg(1)–O4W) 178.5. Each olsalazine in 1 is a double monodentate ligand linking two Mg atoms resulting in a 1 D zig–zag linear structure. All magnesium atoms stand in the vertex of the catenarian structure (as shown in figure 2). Totally different from 1, the crystal of [Ca(L) 4(H2O)] 2 belongs to a tetragonal crystal system, chiral space group P4(3)2(1)2 and Z¼8. The calciums in 2 adoptpentagonal bipyramid coordination mode with one monodentate carboxylate (O3A), one bidentate carboxylate (O5 and O6) of different olsalazine ligands and four water molecules (as shown in figure 3). Olsalazine in 1 was a bidentate bridge, but in 2 is a tridentate bridge linking two calcium atoms in a 1 D zig–zag linear structure (as shown in figure 4). |
