An unusual 32-membered copper(ii) metallomacrocube based on a Cu₄O₃X cubic core: photocatalytic, electrocatalytic, and magnetic properties

Abstract

The first 32-membered Cu(II) cluster with a big cubic structure consisting of eight small cubic cores exhibited a high photocatalytic activity for the degradation of rhodamine B (∼99%) dye within 15 min under UV light irradiation, effective electrocatalytic activity for nitrite reduction and strong antiferromagnetic interactions among the Cu(II) centers.

Structural Chemistry of Giant Metal Based Supramolecules

“…14 Nevertheless, cage complexes can also be called (nano)capsules even if they do not have the ability to encapsulate guest molecules as the name implies. 15−17 The outer shape of a giant molecule can also inspire the name: a cube, 18 (or even metallomacrocube 19 ), a tetrahedron, 14 a cuboctahedron, 20 a metallo-ring, 21 a wheel, 22 a tube, 23 etc. Sometimes the appearance of the giant molecule or ion even resembles objects of everyday life such as an hourglass or a horseshoe (fragments of the metallo-rings 24,25 ), or even a bottlebrush.…”

Self‐Assembly of a Semiconductive and Photoactive Heterobimetallic Metal–Organic Capsule

“…The unusually large negative θ value confirms the existence of strong AF coupling among the metal centers. This may be caused by the effective overlap between the Fe and Co magnetic orbitals owing to their short distances associated with M–M interactions [17a, 19] . Furthermore, the shape of the M/H plots is similar to that of an antiferromagnet, in which the M value increases rapidly at low fields, with no obvious saturation observed up to 70 kOe (Supporting Information, Figure S7).…”
