摘要：

The title compound [systematic name: 9,10-dimethoxy-2,3-methylenedioxy- 5,6-dihydrodibenzo[a,g]quinolizinium formate-succinic acid (1/1)], C20H18NO4+.CHO2-.C4H6O4, contains centrosymmetric pairs of almost planar berberine cations, and hydrogen-bonded (C4H6O4...HCOO-)(2) rings of succinic acid with formate anions, bonded by O-H...O hydrogen bonds with O...O distances of 2.4886 (15) and 2.5652 (16) Angstrom. Pairs of cations and molecules of succinic acid are connected by non-conventional weak C-H...O hydrogen bonds, with C...O distances of 3.082 (2) and 3.178 (2) Angstrom.
