摘要
采用具有手性的席夫碱配体,(R)-1-(1-羟基正丁烷-2-氨甲基)萘-2-醇(H2L),和醋酸铜反应得到四核铜的化合物(Cu4L4)(CH3CN)。用X-射线衍射对化合物的晶体结构进行了测定,结果表明此化合物含有4个铜和4个配体,铜通过配位作用和4个氧原子形成类立方烷中心。磁性测定表明此化合物中金属离子之间有弱的反铁磁相互耦合作用。
An antiferromagnetic complex based on copper(Ⅱ) and chiral Schiff-base ligand (R)-1-((1-hydroxybutan-2-ylimino)methyl)naphthalen-2-ol (H2L) with formula of (Cu4L) (CH3CN) was synthesized and structurally characterized. Single-crystal structure shows that the complex consists of an inorganic core formed by four Cu(Ⅱ)ions and four oxygen atoms from four ligands respectively. Magnetic measurements show that a weak antiferromagnetic coupling occurs in the complex. CCDC: 620500.
