چکیده
The title compound, CH(7)N(4) (+)·C(4)H(5)O(4) (-), is a molecular salt containing discrete amino-guanidinium and succinate ions. The amino-guanidinium cation is nearly planar, with a maximum deviation of 0.035 (1) Å. The dihedral angle between the amino-guanidinium cation and the succinate anion is 3.35 (6)°. The crystal packing exhibits inter-molecular N-H⋯O and O-H⋯·O hydrogen bonds.

In the title compound, C(5)H(8)N(3) (+)·C(4)H(5)O(4) (-), the pyridine N atom of the 3,4-diamino-pyridine mol-ecule is protonated. The protonated N atom participates in an N-H⋯O hydrogen bond to a succinate O atom of the singly deprotonated succinate anion. Each of the two amino groups are hydrogen-bonded to the O atoms of two different sets of succinate groups.. The crystal structure is furthe...
متن کاملStudies on the mechanism of hydrogen exchange between succinate and water catalyzed by the soluble succinic dehydrogenase of Singer from bovine heart.
The equilibrium exchange of hydrogen between the 2,3methylene positions of succinate and water was studied under aerobic conditions with specifically tritiated and deuterated succinates and soluble succinic dehydrogenase prepared by the method of Singer from bovine heart. The exchange of tritium from racemic 2-tritiosuccinate (racemic-T1), racemic 2,3-ditritiosuccinate (racemic-T?), and meso-2,...
