{Cr7Ni} octametallic rings, [nPr2NH2][Cr7NiF8(O2CtBu)16)], have been demonstrated to be potential candidates as ‘qubits’ (quantum bits).[1] However, a limiting step in their use as qubits is the ability to form suitably ordered arrays with switchable magnetic communication. The work presented here focuses on functionalising {Cr7Ni} clusters by substitution of the peripheral carboxylate groups for this purpose to produce [nPr2NH2][Cr7NiF8(O2CtBu)16x(O2CR)], where R is a group with the desired functionality. The use of pyridyl and carboxylic acid containing groups has been investigated for linking {Cr7Ni} units, either through metal sites or metallic clusters. The work has produced multi-component, polymetallic, nano-scale constructs[2,3] where in some cases where the individual building blocks have been presynthesised and isolated prior to synthesis, demonstrating the degree of control with which individual units can be assembled. Examples where three, four and six {Cr7Ni} units are bound to a variety of metal clusters are presented (Figure 1). Along with this, a 3-dimensional framework structure has been successfully synthesised and characterised, an example of a MOF without an organic component that demonstrates the potential for controlled synthesis of extended arrays of {Cr7Ni} units (Figure 2).
