Abstract

Addition of [Mo(V)2O2S2(edt)2]2- (edt =1,2-ethanedithiolate) to acetonitrile and/or methanol solutions of MnII containing bipyridines [4,4'-trimethylenedipyridine (TDP), 4,4'-bipyridine (4,4'-bpy), 2,2'-bipyridine (2,2'-bpy)] or 15-crown-5 produces three new heterometallic cluster coordination polymers, [Mn2[Mo2O2S2(edt)2]2(TDP)3(CH3OH)2(NCMe)2].3CH3OH.0.25MeCN (1), [Mn(TDP)2(H2O)2]2+[Mn[Mo2O2S2(edt)2)2(TDP)2]]2-.6CH3OH (2), [MnMo2O2S2(edt)22(CH3OH)(H2O)].CH3OH (3), and three new multinuclear clusters, [MnMo2O2S2(edt)2(CH3OH)4].0.5(4,4'-bpy) (4), [MnMo2O2S2(edt)22].2CH3OH (5), and (NEt4)2[Mn(15-crown-5)[Mo2O2S2(edt)2]2] (6). All compounds were characterized by X-ray crystallography. The coordination mode of Mn in these compounds depends on the ligands and the crystallization conditions. Compound 2 readily converts to 1 or 3 depending on the reaction and solvent conditions. Compounds 1 and 2 were analyzed using thermogravimetric analysis combined with mass spectroscopy (TG-MS) in the temperature range 25-500 degrees C. The room-temperature magnetic moments for compounds 1-6 were determined.

摘要

向含有联吡啶[4,4'-三亚甲基联吡啶(TDP)、4,4'-联吡啶(4,4'-bpy)、2,2'-联吡啶(2,2'-bpy)]或15-冠-5的MnII的乙腈和/或甲醇溶液中加入[Mo(V)2O2S2(edt)2]2-(edt = 1,2-乙二硫醇盐)，得到三种新的异金属簇配位聚合物，[Mn2[Mo2O2S2(edt)2]2(TDP)3(CH3OH)2(NCMe)2].3CH3OH.0.25MeCN (1)、[Mn(TDP)2(H2O)2]2+[Mn[Mo2O2S2(edt)2)2(TDP)2]]2-.6CH3OH (2)、[MnMo2O2S2(edt)22(CH3OH)(H2O)].CH3OH (3)，以及三种新的多核簇合物，[MnMo2O2S2(edt)2(CH3OH)4].0.5(4,4'-bpy) (4)、[MnMo2O2S2(edt)22].2CH3OH (5)和(NEt4)2[Mn(15-冠-5)[Mo2O2S2(edt)2]2] (6)。所有化合物均通过X射线晶体学进行表征。这些化合物中Mn的配位模式取决于配体和结晶条件。化合物2根据反应和溶剂条件容易转化为1或3。在25至500摄氏度的温度范围内，使用热重分析结合质谱(TG-MS)对化合物1和2进行了分析。测定了化合物1-6的室温磁矩。
