In the title compound, (C8H12N)2[Co(H2P2O7)2(H2O)2], the Co(2+) ion lies on a crystallographic inversion centre and adopts a slightly distorted octa-hedral CoO6 coordination geometry arising from two chelating diphosphate H2P2O7 ligands and two trans water mol-ecules. In the crystal, the components are linked by O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds and weak aromatic π-π stacking [shortest centroid-centroid separation = 3.778 (2) Å] inter-actions. (001) layers of alternating organic cations and complex inorganic anions are apparent.
在标题化合物（C8H12N）2[Co（H2P2O7）2（H2O）2]中，Co（2+）离子位于一个晶体学反演中心上，由于两个螯合的二磷酸根H2P2O7配体和两个反位水分子，呈现出略微扭曲的八面体CoO6配位几何构型。在晶体中，各组分通过O-H⋯O、N-H⋯O和C-H⋯O氢键以及弱的芳香π-π堆积[最短质心-质心间距 = 3.778 (2) Å]相互作用相连。明显存在交替排列的有机阳离子和复杂无机阴离子的（001）层。
