Source of materials

The 1,3-bis[(1H-imidazol-1-yl)methyl]benzene ligand was synthesized according to the reported method [4]. All other chemicals of reagent grade were commercially available and used without further purification. Here 0.2 mmol 1,3-bis[(1H-imidazol-1-yl)methyl]benzene, 0.2 mmol D-camphoric acid, 0.2 mmol cadmium sulfate octahydrate, 0.4 mmol sodium hydroxide and 15 ml water were mixed and placed in a thick Pyrex tube, which was sealed and heated to 403 K for 72 h. The tube was spontaneously cooled to ambient temperature, whereupon pale yellow block crystals were obtained. Calcd. For C48H56Cd2N8O8: C, 52.52%; H, 5.10%; N, 10.21%; Found: C, 51.16%; H, 5.19%; N, 10.05%.

Experimental details

H atoms were positioned geometrically and allowed to ride on their parent atoms, with C—H = 0.93 Å (phenyl & imidazolyl), 0.96 Å (methyl), 0.97 Å (methylene) or 0.98 Å (methylidyne) and with Uiso(H) = 1.2Ueq(C). One D-camphorate (C45, C46, C47 and C48) is disordered over two positions and was refined with site occupancies of 0.612 and 0.388.

Comment

Metal-organic frameworks has attracted much attention in the fields of supramolecular chemistry and crystal engineering [5], [6], [7], [8], [9]. According to the previously reported studies, imidazole and its derivatives such as 1,4-di(1-imidazolyl)benzene [10], 1,3-di(1-imidazolyl)benzene [11], 1,3,5-tris(1-imidazolyl)benzene [12], 1,4-bis(imidazol-1-ylmethyl)benzene [13], 1,3-bis(imidazol-1-ylmethyl)benzene [14], 1,2-bis(imidazol-1-ylmethyl)benzene [14], 1,3-bis(1-imidazolyl)-5-(imidazol-1-ylmethyl)benzene [15] 1,2-bis(imidazol-1-ylmethyl)benzene,1,3,5- tris[(1H-imidazol-1-yl)methyl]benzene [16] etc., have been widely employed as organic ligands to construct metal-organic coordination frameworks. Additionally, D-camphorate has been used as a bridging ligand, owing to its naturally chirality, and has been extensively employed in the construction of chiral polymers with different framework topologies [13, 14, 17, 18].

The title complex crystallizes in the monoclinic space P21, the asymmetric unit consists two crystallographically independent CdII centres, two 1,3-bis[(1H-imidazol-1-yl)methyl]benzene(1,3-bimb) ligands and two D-cam2− ligands. Each Cd2+ cation is coordinated by two N atoms from two different 1,3-bimb ligands and four O atoms from two individual D-cam2− ligands, in a distorted octahedral geometry. Atom Cd1 is coordinated by atoms N1, N5, O3, O4, O5 and O6, and Cd2 is surrounded by atoms N3, N8 i , O1, O3, O7 i and O8 i [symmetry codes:(i) −x + 1, −y + 1, −z]. The Cd—N bond lengths range from 2.225(7) to 2.275(5) Å and the Cd—O bond lengths vary from 2.309(5) to 2.399(7) Å, which are in the normal ranges observed in the previously reported Cd(II) complex [13]. Both carboxylate groups of the D-cam2− anion are deprotonated and chelate to two Cd atoms (Cd1 and Cd2), the O—Cd—O bite angle are 54.87(19)(O3—Cd1—O4), 55.61(15)(O5—Cd1—O6), 54.92(19)(O1—Cd2—O2) and 55.35(19)° (O7 i —Cd1—O8 i ), respectively. The 1,3-bimb ligand employs a Z-shape conformations and coordinates to two Cd(II) centres (Cd1 and Cd2). In the Z1, the dihedral angles between the least-squares plane of the central ring of the 1,3-bimb ligand and those of the coordinated terminal imidazole groups are 78.39(5) (N1C1N2C2C3) and 87.86(3)° (N3C12N4C14C13), and the planes of the imidazole rings of the 1,3-bimb ligand are oriented with respect to each other at an angle of 14.78(4)°. Those are in accord with that found in the Z2 [77.50(6) (N5C15N6C17C16), 88.00(4) (N7C26C27N8C28) and 16.81(5)°, respectively]. Adjacent Cd(II) metal centres are doubly bridged by D-cam2− and 1,3-bimb ligands, resulting in a double-stranded chain running parallel to the [1 1 0] direction. In the double-stranded structure, the Cd···Cd distances are 9.53(5) (Cd1···Cd2), 9.56(1) (Cd1 i ···Cd2) and 18.91(7) Å (Cd1···Cd1 i  = Cd2···Cd2 ii ) [symmetry codes: (i) −x + 1, −y + 1, −z; (ii) −x + 1, −y + 1, z]. In the crystal structure, neighboring chains are linked by weak but extensive intermolecular C—H···O hydrogen bonds, generating a three-dimensional supramolecular network structure.
