The neutral holmium(III) oxalate octadecahydrate {[Ho 2 (ox) 3 (H 2 O) 6 ]·12H 2 O} n of mixed hexagonal/decagonal (6 3 ·10 3 ) 3D net topology shows important changes in the magnetocaloric efficiency upon dehydration/rehydration by heating and water vapor exposition to give the holmium(III) oxalate decahydrate {[Ho 2 (ox) 3 (H 2 O) 6 ]·4H 2 O} n of hexagonal (6 3 ) 2D net topology through the intermediacy of the elusive amorphous anhydrous compound {Ho 2 (ox) 3 } n .
