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), ButCH2CO2H, 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.
