Abstract:
In the title coordination polymer, {[Mn(C(7)H(3)NO(4))(H(2)O)(2)]·2H(2)O}(n), the Mn(II) ion is coordinated in a distorted octahedral environment by the O atoms of two water mol-ecules, one N and one O atoms of the chelating pyridine-2,3-dicarboxyl-ate (PDC) dianion, and two axial bridging carboxyl-ate O atoms from two adjacent PDC ligands. The fully deprotonated PDC anion acts a μ(3)-bridging ligand, establishing a chain structure along the a axis. These polymeric chains are connected into a three-dimensional framework via several inter-molecular O-H⋯O hydrogen bonds.

The formation of hydrates is a reversible reaction. Hydrate formation is influenced by steric and electronic factors accompanying the alkyl substituents on the carbonyl group: The rate of hydrate formation increases with a decrease in the number of alkyl groups attached to the carbonyl carbon. Hence,...
