| 摘要: 本文报道2个镍/4-磺基苯甲酸/1，10-邻菲咯啉配合物的合成、表征、结构和性质。配合物[Ni(4-sb)(phen)(H2O)2]·(2H2O) (1)是单核结构，配合物[Ni(phen)3]·(4-Hsb)(OH)(8H2O) (2)是1个阳离子与阴离子复合物。在这2个配合物中金属镍的配位形式均是六配位八面体构型，Ni-N键长相近。2个配合物的扩展结构均为三维网络结构。配合物2中阳离子占据由阴离子与水分子形成的三维网络孔道。配合物2是一个羧基氢未脱去同时又有氢氧根的分子。 |

| Abstract: Two diverse complexes, [Ni(4-sb)(phen)(H2O)2]·(2H2O) (1) and [Ni(phen)3]·(4-Hsb)(OH)(8H2O) (2) where 4-sb is 4-sulfobenzoate dianion and phen is 1,10-phenanthroline, have been synthesized and characterized by elemental analyses, TGA, molar conductance, UV-Vis, fluorescent spectra and single-crystal structure determination. Complex 1 is a monomer, while complex 2 is a cation-anion species. Nickel atoms in both complexes afford an octahedral coordination geometry and all Ni-N lengths are close. Two extending structures for complexes 1 and 2 are three-dimensional hydrogen-bonding network. The cations in complex 2 occupy the three-dimensional channels constructed by anions and water molecules. Interestingly, co-existence of base and acid in complex 2 is observed.
