The large-scale synthesis of C60 has stimulated considerable interest in the chemistry and structures of metal fullerides. Studies on compounds formed by C60 with metal-organic complexes have shown that some metal atoms can form bonds with the C60 molecules. Nagashima et al. have proposed that one-, two-, or three-dimensional polymers may be formed when Pd atoms link neighboring C60 molecules by being coordinated with the π electrons at the double-bond regions between hexagonal carbon rings. In the present study, PdnC60 (n= 1,3,4) were prepared from C60 and a Pd0 precursor by a liquid chemical combination method. The compositions of these compounds were determined with EELS. Their structures were examined with a Topcon 002B and a JEM-2000FX HRTEM.The electron micrographs and diffraction patterns of the Pd1C60 preparation showed regions of small Pd crystals embedded in near-amorphous carbon and also regions of heavily faulted FCC C60 structures. Fig. 1 is a HRTEM image showing a region of FCC structure viewed in the [110] direction with several groups of stacking faults.

Two new two-dimensional copper(II) coordination polymers, [Cu(L)(BDC)]_H2O (1) and [Cu2(L)0:5(SIP)(OH)(H2O)] 2H2O (2) [L=N;N0-bis(3-pyridylamide)-1,6-hexane, H2BDC=1,3- benzenedicarboxylic acid, H3SIP=5-sulfoisophthalic acid (3,5-dicarboxybenzenesulfonic acid)], have been synthesized hydrothermally by self-assembly of the flexible bis-pyridyl-bis-amide ligand L and the aromatic polycarboxylate ligands H2BDC or H3SIP. X-Ray diffraction analysis reveals that complex 1 displays a metal-organic coordination layer with a binodal (3,5)-connected {42.67.8}{42.6} topology, in which the L ligands adopt a m2-bridging mode (via ligation of the pyridyl nitrogen atoms). Complex 2 also exhibits a layered network based on tetranuclear copper clusters [Cu4(μ3-OH)2(H2O)2(O2C-)4], L ligands and SIP anions, showing a binodal (4,8)-connected network with {414.610.84}{44.62} topology, in which the L ligands adopt a μ6-bridging coordination mode (via ligation of the pyridyl nitrogen and carbonyl oxygen atoms). Adjacent layers in 1 and 2 are further linked by hydrogen bonding interactions to form three-dimensional supramolecular frameworks. The electrochemical behavior of the two complexes in bulk-modified carbon paste electrodes has been investigated

The self-assembly of coordination polymers and the crystal engineering of metal–organic coordination frameworks have attracted great interest, but it is still a challenge to predict and control the compositions and structures of the complexes. Employing multidentate organic ligands and suitable metal ions to construct inorganic–organic hybrid materials through metal–ligand coordination and hydrogen-bonding interactions has become a major strategy. Recently, imidazole-containing multidentate ligands that contain an aromatic core have received much attention. A new three-dimensional MnIIcoordination polymer based on 1,3,5-tris[(1H-imidazol-1-yl)methyl]benzene, namely poly[(ethane-1,2-diol-κO)(μ-sulfato-κ2O:O′){μ3-1,3,5-tris[(1H-imidazol-1-yl)methyl]benzene-κ3N:N′:N′′}manganese(II)], [Mn(SO4)(C18H18N6)(C2H6O2)]n, was synthesized and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. Crystal structural analysis shows that there are two kinds of crystallographically independent MnIIcentres, each lying on a centrosymmetric position and having a similar six-coordinated octahedral structure. One is coordinated by four N atoms from four 1,3,5-tris[(1H-imidazol-1-yl)methyl]benzene (timb) ligands and two O atoms from two different bridging sulfate anions. The second is surrounded by two timb N atoms and four O atoms, two from sulfate anions and two from two ethane-1,2-diol ligands. The tripodal timb ligand bridges neighbouring MnIIcentres to generate a two-dimensional layered structure running parallel to theabplane. Adjacent layers are further bridged by sulfate anions, resulting in a three-dimensional structure with3,4,6-ctopology. Thermogravimetric analysis of the title polymer shows that it is stable up to 533 K. The first weight loss between 533 and 573 K corresponds to the release of coordinated ethane-1,2-diol molecules, and further decomposition occurred at 648 K.
