A four-shell, 136-metal 3d-4f heterometallic cluster approximating a rectangular parallelepiped†
Abstract
A nanosized heterometallic cluster containing 60 La(III) and 76 Ni(II) ions, which are arranged into a four-shell, nest-like framework structure, was obtained by the hydrolytic reaction of the mixed La(NO3)3–Ni(NO3)2 system using
