Abstract

Gaining control of the building blocks of magnetic materials and thereby achieving particular
characteristics will make possible the design and growth of bespoke magnetic devices. While progress
in the synthesis of molecular materials, and especially coordination polymers, represents a significant step
towards this goal, the ability to tune the magnetic interactions within a particular framework remains in its
infancy. Here we demonstrate a chemical method which achieves dimensionality selection via preferential
inhibition of the magnetic exchange in an S ¼ 1=2 antiferromagnet along one crystal direction, switching
the system from being quasi-two- to quasi-one-dimensional while effectively maintaining the nearestneighbor
coupling strength.
