while 7 had a diamagnetic ground state. The different magneticproperties are due to the small structural differences in the diamond chain units, because the sign and intensity of magnetic coupling between the neighbouring copper ions are sensitive to the bridging structures. Copper hydroxide compounds with different organic ions and diverse structures prepared by this hydrolysis method will facilitate

A new family of lanthanide disulfonates Ln(OH)(NDS)(H2O), (Ln = La, Pr and Nd; NDS=1,5-naphthalenedisulfonate) was designed and hydrothermally synthesized; this is the first example of a disulfonate ligand coordinated to six different Ln atoms; these materials, with high thermal stability, act as active and selective bifunctional catalysts in oxidation and epoxide ring opening; strong luminescence from the optically active Nd center was observed.
Proton‐Conducting Hydrogen‐Bonded 3D Frameworks of Imidazo‐Pyridine‐Based Coordination Complexes Containing Naphthalene Disulfonates in Rhomboid Channels
Coordinationcomplexes of an olefinic molecule (PIP) containingpyridine and imidazopyridine moieties with ZnII /NiII metal salts were shown to exhibit appreciable proton conductivity. These complexes form 3D-hydrogen bondedframeworkscontainingrhomboidalchannels that are occupied by uncoordinated 1,5-naphthalenedisulfonate (NDS). The extensive hydrogen bonding between the frameworks and NDS resulted
包含吡啶和咪唑并吡啶部分的烯烃分子(PIP)与ZnII / NiII金属盐的配位配合物显示出可观的质子传导性。这些复合物形成3D氢键结合的骨架,其中包含由未配位的1,5-萘二磺酸盐(NDS)占据的菱形通道。构架与NDS之间广泛的氢键结合形成了热稳定且不溶于水的材料。不管存在的金属原子如何,这两种络合物均表现出中等至高质子传导性,具体取决于温度和湿度水平,其范围为10-5至0.5×10-3 S cm-1。
