Abstract

In the title cobalt(II) complex with 2-methyl­anilinium and diphosphate, (C7H10N)2[Co(H2P2O7)2(H2O)2], a three-dimensional network is built up from anionic layers of [Co(H2P2O7)2(H2O)2]2− units and 2-methyl­anilinium cations located between these layers. The dihydrogendiphosphate groups present a bent eclipsed conformation, while the Co2+ ions lie on inversion centers. An intricate network of O—H⋯O and N—H⋯O hydrogen bonds is established between the different components, assuring the cohesion of the network with other inter­actions, being of electrostatic and van der Waals nature.
