以1-（2-吡啶）-3-（2-吡咯）乙酰丙酮为原料，通过一锅法合成了一种铜铁杂金属车轮分子[CuII 6 FeIII（HL）6-（OH）2（OCH 3）4]（NO3）3·6 H2O（1·6 H2O）（H2 L = 1-（2-吡啶）3-（2-吡咯）乙酰丙酮）。X射线结构分析表明，七核轮簇由六个Cu（II）离子包围的中心Fe（III）离子，通过甲氧基和羟基桥连接。低温磁性研究表明分子内反铁磁相互作用是有效的。
A heterometal Cu6Fe wheel molecule, [CuII6FeIII(HL)6- (OH)2(OCH3)4](NO3)3¢6H2O (1¢6H2O) (H2L = 1-(2-pyridine) 3-(2-pyrrole)acetylacetone) was synthesized by the one-pot reaction of H2L with copper and iron sources. X-ray structural analysis reveals that the heptanuclear wheel cluster consists of a central Fe(III) ion surrounded by six Cu(II) ions, linked through methoxo- and hydroxo-bridges. Cryomagnetic studies indicate intramolecular antiferromagnetic interactions were operative.
