The structure of the mixed zinc cobalt diphosphate ZnCoP2O7 presents a low-dimensional system never previously observed in diphosphates of 3d transition elements. The paramagnetic Co2+ ions are grouped into dimers linked by P2O74- groups, forming tunnels in which the diamagnetic Zn2+ ions are located. The metal environments can be described as a distorted octahedron and a distorted square-based pyramid, for Co and Zn respectively, the two coordination polyhedra sharing common edges through the O atoms O1-O2 and O6-O7.
