各位高手，谁能帮我翻译下这段文字啊，看得太累了，谢谢了 Therefore, 1H-benz- imidazole-5,6-dicarboxylic acid (H3bidc) is an outstanding candidate ligand to construct d–f HMCPs as it is a multidentate rigid ligand with O-donors and N-donors and possesses diverse coordination modes with different metal ions. Moreover, the distance between the N-donors and O-donors in H3bidc is large enough to overcome steric hindrance. In addition H3bidc can be used to assemble HMCPs with interpene- trated frameworks. Our group reported Ln–Ag HMCPs with doubly interpenetrated frameworks constructed from the H3bidc ligand。 To the best of our knowledge, 3d–4f HMCPs constructed by H3bidc ligands have not yet been reported, although 3d–4f HMCPs have been widely investigated, of which most are Cu–Ln systems.11 However, the number of reported Ni–Ln HMCPs is relatively limited and they are mainly cluster com- plexes or low-dimensional complexes.12 Therefore, the synthesis of higher dimensional Ni–Ln HMCPs complexes is of great importance. Based on the above-mentioned points, our aim is to synthesize 3d–4f HMCPs with novel frameworks bearing noteworthy prop- erties by using NiSO •7H O, rare earth oxides and H bidc ligands. Herein, we report the synthesis, structural characteriz- ation and properties of a family of [Ln2Ni(Hbidc)2(SO4)2- (H2O)8]n HMCPs [Ln = Pr (1), Sm (2), Eu (3), Gd (4), Tb (5), Dy (6), Ho (7), Er (8), Yb (9)]. Structure determination revealed that all compounds have a three-dimensional network and the lanthanide contraction has a significant influence on the structure transformation. The luminescence properties of HMCPs 1–9 were studied, and several of the HMCPs exhibit the characteristic transitions of the corresponding lanthanide ions. The magnetic properties of HMCPs 4 and 6–8 were measured, revealing that ferromagnetic coupling is present in 4. [ Last edited by winter_north on 2013-2-20 at 00:06 ] |

To the best of our knowledge, 3d–4f HMCPs constructed by H3bidc ligands have not yet been reported, although 3d–4f HMCPs have been widely investigated, of which most are Cu–Ln systems.11 However, the number of reported Ni–Ln HMCPs is relatively limited and they are mainly cluster com- plexes or low-dimensional complexes.12 Therefore, the synthesis of higher dimensional Ni–Ln HMCPs complexes is of great importance. 就我们所知，由 H3bidc配体创建起的3d–4f HMCPs还没有被报道过，尽管3d–4f HMCPs，其中大部分是Cu-Ln体系，已经被广泛研究。然而， 被报道过的Ni-Ln HMCP的数量相对有限，而且它们主要是簇复合物或者是低维复合物。因此，合成高维Ni–Ln HMCPs复合物是很重要的。 先翻这段，下面的接力。 |
