Propane-1,2-diaminium bis-(pyridine-2,6-dicarboxyl-ato-?O,N,O)cadmate dihydrate.


ABSTRACT: The reaction of cadmium nitrate dihydrate, propane-1,2-diamine and pyridine-2,6-dicarb-oxy-lic acid in a 1:1:2 molar ratio in an aqueous solution resulted in the formation of the title compound, (C(3)H(12)N(2))[Cd(C(7)H(3)NO(4))(2)]·2H(2)O or (p-1,2-daH(2))-[Cd(pydc)(2)]·2H(2)O (where p-1,2-da is propane-1,2-diamine and pydcH(2) is pyridine-2,6-dicarb-oxy-lic acid). The Cd(II) ion is coordinated by four O and two N atoms of two pydc ligands in a distorted octa-hedral environment. The structure also contains two uncoordinated water mol-ecules. In the crystal, there are several inter-molecular N-H?O, O-H?O and weak C-H?O hydrogen bonds. There are also ?-? stacking inter-actions between the pyridine rings of pydc units, with centroid-centroid distances of 3.4708?(16)?Å.
