4-Amino-pyridinium 4-carb-oxy-butano-ate.

ABSTRACT: The asymmetric unit of the title salt, C(5)H(7)N(2) (+)·C(5)H(7)O(4) (-), contains two 4-amino-pyridinium cations and two 4-carb-oxy-butano-ate anions. Each 4-amino-pyridinium cation is planar, with a maximum deviation of 0.005?(2)?Å. Both 4-carb-oxy-butano-ate anions adopt an extended conformation. In the crystal structure, the cations and anions are linked via N-H?O, O-H?O and C-H?O hydrogen bonds, forming a two-dimensional network parallel to the bc plane.

2,6-Di-amino-4-chloro-pyrimidinium 4-carb-oxy-butano-ate.

Project description:In the title mol-ecular salt, C4H6ClN4 (+)·C5H7O4 (-), the cation is essentially planar, with a maximum deviation of 0.037?(1)?Å for all non-H atoms. The anions are self-assembled through O-H?O hydrogen bonds, forming a supra-molecular zigzag chain with graph-set notation C(8).

2-Amino-3-carb-oxy-pyridinium perchlorate.

Project description:The asymmetric unit includes two crystallographically independent equivalents of the title salt, C(6)H(7)N(2)O(2) (+)·ClO(4) (-).

Further C-H?O contacts connect these layers, forming a three-dimensional network, in which R(4) (4)(20) rings and C(2) (2)(11) infinite chains can be identified.
