Phenanthroline–manganese inclusion complexes of dicarboxylic acid containing extensive hydrogen-bonding interactions

Two phenanthroline–manganese inclusion complexes with [MnCl(H2O)(phen)2]+ core were prepared in the presence of dicarboxylic acid and their structures were determined. Uncoordinated adipic acid and phthalic acid as guest molecules are included in the complexes with formulas {[MnCl(H2O)(phen)2]Cl}2·C6H10O4·8H2O (1) and {[MnCl(H2O)(phen)2]Cl}4·2C8H6O4·4H2O (2). The dicarboxylic acid molecules together with aqua and Cl− ligands, Cl− anions and solvate H2O molecules form extensive hydrogen-bonding interactions, building up supramolecule-like aggregate structure.
