Five novel arylsulfonates of Ni and Co have been hydrothermally obtained and their structures determined by X-ray single-crystal diffraction. Ni(Phen)(H2O).2H2O (1) is a hydrogen-bonded supramolecular layered compound formed by self-assembly of tetraaqua-o-phenanthrolinenickel(II) cations and 1,5-naphthalenedisulfonate anions, [Ni(Phen)2(H2O)(1,5-NDS)] (2) and [Ni(Phen)2(H2O)(2,6-NDS)].2H2O (4) exhibit 2D structures via O-H...O and pi-pi (both perfect face-to-face and parallel-displaced) stacking interactions, [Co(Phen)2(H2O)(1,5-NDS)].2H2O (5) presents a 3D structure via O-H...O hydrogen-bond layers and pi-pi parallel-displaced stacking interactions, and [Co(Phen)2(1,5-NDS)] (3) is the first example of a covalently bonded polymeric cobalt sulfonate. Its 1D structure comprises chains formed through bitopic 1,5-NDS linkers. Rates and selectivities for oxidation of organic sulfides with H2O2 were measured with 2-5.
通过水热法合成了五种新型的镍和钴的芳基磺酸盐，并通过X射线单晶衍射确定了它们的结构。Ni(Phen)(H₂O)·2H₂O (1) 是一种氢键超分子层状化合物，由四水合邻菲罗啉镍(II)阳离子和1,5-萘二磺酸盐阴离子自组装形成，[Ni(Phen)₂(H₂O)(1,5-NDS)] (2) 和 [Ni(Phen)₂(H₂O)(2,6-NDS)]·2H₂O (4) 通过O-H...O和π-π（完美面对面和平行错位）堆积相互作用呈现二维结构，[Co(Phen)₂(H₂O)(1,5-NDS)]·2H₂O (5) 通过O-H...O氢键层和π-π平行错位堆积相互作用呈现三维结构，而 [Co(Phen)₂(1,5-NDS)] (3) 是共价键合的聚合钴磺酸盐的首个实例。其一维结构由通过双齿1,5-NDS连接体形成的链组成。用2-5测定了用H₂O₂氧化有机硫化物的速率和选择性。
