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

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 t...

Description
Summary: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. [Display omitted] •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.
