Rare nuclearities in Ni(ii) cluster chemistry: a Ni11 cage from the first use of N-salicylidene-2-amino-5-chlorobenzoic acid in metal cluster chemistry

Abstract

The reaction between N-salicylidene-2-amino-5-chlorobenzoic acid (sacbH₂), Bu^tCH₂CO₂H, and Ni(ClO₄)₂·6H₂O leads to a new Ni₁₁ cluster comprising Ni₄ squares and Ni₃ triangles; the compound is antiferromagnetically-coupled with an S = 1 spin ground state and low-lying excited states populated even at the lowest accessible temperatures.
