讨论了基于氢键和形状互补性的有机-有机金属晶体的工程。合成了顺磁性阳离子[（η6-C6 H6）2Cr][（CHD）4]（1）和[（η6-C6 H5 Me）2Cr][（CHD）2]（2），其中顺磁性阳离子[（η6-C6 H6）2Cr]+和[（η6-C6 H5 Me）2Cr]+被包裹在1，3-环己二酮（CHD）衍生的有机阴离子骨架中。这种晶体合成的想法源于Etter等人（J. Am. 1986，108，5871）。晶体通过超分子[（CHD）2]-·（CHD）2和[（CHD）2]-阴离子之间的O−H··O氢键以及阴离子和有机金属阳离子之间的C−H··O氢键结合在一起。合成了[（η_6-C_6H_6）_2Cr][OH]·3H_2O（3）和[（η_6-C_6H_6）_2Cr][CHD]·3H_2O（4）两种水合晶体，并对其结构进行了表征。晶体通过O−H···O和C−H···O相互作用结合在一起，水分子也参与其中。水...
The engineering of organic−organometallic crystals based on hydrogen bonding and on shape complementarity is discussed. The crystalline salts [(η6-C6H6)2Cr][(CHD)4] (1) and [(η6-C6H5Me)2Cr][(CHD)2] (2), in which the paramagnetic cations [(η6-C6H6)2Cr]+ and [(η6-C6H5Me)2Cr]+ are encapsulated within organic anion frameworks derived from 1,3-cyclohexanedione (CHD), have been constructed. The idea of this crystal synthesis stems from the structure of the host−guest cyclamer (CHD)6·(C6H6) prepared by Etter et al. (J. Am. Chem. Soc. 1986, 108, 5871). The crystals are held together by O−H···O hydrogen bonds between the supramolecular [(CHD)2]-·(CHD)2 and [(CHD)2]- anions and by C−H···O hydrogen bonds between the anions and the organometallic cations. The hydrated crystalline species [(η6-C6H6)2Cr][OH]·3H2O (3) and [(η6-C6H6)2Cr][CHD]·3H2O (4) have also been prepared and structurally characterized. The crystals are held together by O−H···O as well as C−H···O interactions involving the water molecules. The hydroxi...
