We present a comparative study of the low-dimensional compounds α- and β-TeVO₄. Our data clearly show
that the change in the local coordination geometry of V⁴⁺ ions comparing α- and β-TeVO₄ leads to a drastic differences
in the magnetic properties. Despite sharing the same crystal structure, the two compounds realize different
magnetic exchange topologies. Both compounds exhibit a transition from ferro- to antiferromagnetic correlations
with decreasing temperature. This effect however is driven by different mechanisms for both compounds.
Additionally, a dimensional crossover is found in β-TeVO₄.
