All aligned : A cubic 3d 5 –4f 7 network of Mn 2+ and Gd 3+ ions is assembled by oxydiacetate (O(CH 2 CO 2 − ) 2 ). The network, which is reminiscent of Prussian blue analogues (see picture; Gd coordination polyhedra: purple, Mn coordination polyhedra: blue, [Mn(H 2 O) 6 ] 2+ : green, H 2 O: red), has a weak but definite ferromagnetic interaction.
