    (Figure Presented) Cool stuff: The usage of phosphonates has led to formation of a family of 3d-4f heterometallic cages with a Wells-Dawson-like structure (see picture; Gd, Dy, or Y purple; Ni cyan; P green; O orange; C gray). Magnetic studies show ferromagnetic interactions within the oxocentered nickel triangle and huge entropy change in the Gd analogue, which, in principle, can be used as an ultralow-temperature coolant. © 2011 Wiley-VCH Verlag GmbH & Co.
