A high-nuclearity [Cu6Cd4] antiferromagnet with a supertetrahedral configuration

• A high-nuclearity mixed d-metal cluster based on pentaerythritol has been synthesized and characterized.
• Compound 1 consists of a supertetrahedral Cd(II) cage, which further extended to a CsCl-like 8-connected topology.
• Compound 1 is an antiferromagnet.

A heterometallic coordination cluster with the formula of {[Cu6Cd4(HL)4(piv)8(H2O)6]·4MeOH} (1, H4L = pentaerythritol, Hpiv = pivalic acid) has been synthesized. Compound 1 crystallizes in the tetragonal space group I-4, and consists of a supertetrahedral cage with four Cd(II) and six Cu(II) ions held together by μ3-O bridges. Magnetic susceptibility exhibits that compound 1 is an antiferromagnet.

A high-nuclearity mixed d-metal cluster based on pentaerythritol (H4L), consisting of a supertetrahedral [Cd4Cu6] cage, has been synthesized and characterized and suggests to be an antiferromagnet.Figure optionsDownload as PowerPoint slide
