An organic–inorganic hybrid compound, catena‐poly[bis(3H‐imidazol‐1‐ium) [[tetracyanido‐κ4C‐cobalt(III)]‐μ‐cyanido‐κ2C:N‐[diaqualithium(I)]‐μ‐cyanido‐κ2N:C]], {(C3H5N2)2[CoLi(CN)6(H2O)2]}n, was synthesized by the reaction of Li3[Co(CN)6] with imidazolium chloride in aqueous solution. The compound crystallizes in the monoclinic space group C2/c (data collected at 273 K). In the crystal structure, neighbouring [Co(CN)6]3− anionic units are linked by Li+ cations through the cyanide groups in a trans mode, forming a one‐dimensional zigzag chain structure extending along the c axis. A three‐dimensional supramolecular network is formed through hydrogen‐bonding interactions and is further stabilized by weak CN...π interactions between the cyanide groups and the imidazolium cations. 相似文献

Cyanide as a bridge can be used to construct homo‐ and heterometallic complexes with intriguing structures and interesting magnetic properties. These ligands can generate diverse structures, including clusters, one‐dimensional chains, two‐dimensional layers and three‐dimensional frameworks. The title cyanide‐bridged CuII–CoIII heterometallic compound, [CuIICoIII(CN)6(C4H11N2)(H2O)]n, has been synthesized and characterized by single‐crystal X‐ray diffraction analysis, magnetic measurement, thermal study, vibrational spectroscopy (FT–IR) and scanning electron microscopy/energy‐dispersive X‐ray spectroscopy (SEM–EDS). The crystal structure analysis revealed that it has a two‐dimensional grid‐like structure built up of [Cu(Hpip)(H2O)]3+ cations (Hpip is piperazinium) and [Co(CN)6]3− anions that are linked through bridging cyanide ligands. The overall three‐dimensional supramolecular network is expanded by a combination of interlayer O—H...N and N—H...O hydrogen bonds involving the coordinated water molecules and the N atoms of the nonbridging cyanide groups and monodentate cationic piperazinium ligands. A magnetic investigation shows that antiferromagnetic interactions exist in the title compound. 相似文献

By using environmentally friendly K3[Co(CN)6] as a cyanide source, the solvothermal reaction of CuCl2 and tetrazole (Htta) led to a novel tetrazolate‐ and cyanide‐bridged three‐dimensional heterometallic CuII–CoIII complex, namely poly[[hexa‐μ2‐cyanido‐κ12C :N‐pentakis(μ3‐tetrazolato‐κ3N 1:N 2:N 4)cobalt(III)tetracopper(II)] monohydrate], {[CoIIICuII4(CHN4)5(CN)6]·H2O}n , (I). The crystal structure analysis reveals that it is the first example of a (6,8,8)‐connected three‐dimensional framework with a unique topology, constructed from anionic [Co(CN)6]3− and cationic [(Cu1)2(tta)2]2+ and [(Cu2Cu3)(tta)3]+ units through μ2‐cyanide and μ3‐tetrazolate linkers. The compound was further characterized by thermal analysis, vibrational spectroscopy (FT–IR), scanning electron microscopy/energy‐dispersive X‐ray spectroscopy (SEM–EDS) and magnetic measurements. The magnetic investigation indicates that the complex exhibits antiferromagnetic coupling between adjacent CuII cations. 相似文献
