| 摘要: 本文利用水热法合成了两个新型一价铜配合物[Cu2(ophen)2]·H2O的类同质多晶结构（1α和1β）和一个混合价的铜配合物[Cu2(obpy)2(NO3)]·H2O (2)。晶体结构分析表明：1α显现出于无水的类似物[Cu2(ophen)2]相同的堆积方式，1β则形成出新奇的空间堆积。混合价化合物2是完全离域的，通过氢键集聚体[(H2O)2(NO3-)2]将两个[Cu2(obpy)2]+单元连接起来形成哑铃状的四核结构。 |

| Abstract: Two new pseudo-polymorphs [CuⅠ2(ophen)2]·2H2O (1α and 1β) of the trimorphic [CuⅠ2(ophen)2] (Hophen=1H-[1,10]phenanthrolin-2-one), as well as a mixed-valent copper(Ⅰ,Ⅱ) complex [Cu2(obpy)2(NO3)]·H2O (2) (Hobpy=1H-[2,2′]bipyridinyl-6-one) were hydrothermally prepared at 130～140 ℃. 1β possesses a new molecular packing pattern of the planar [CuⅠ2(ophen)2] molecules, whereas that of its supramolecular isomer 1α is identical to that of β-[CuⅠ2(ophen)2]. In 2, a new hydrogen-bonded aggregate [(H2O)2(NO3-)2] links two [Cu2(obpy)2]+ moieties to form the dumbbell-like structure similar to the dicarboxylate-linked tetranulear analogues described previously, in which the valence of the copper atoms is delocalized. CCDC: 247025～247027. |
