Diaqua­bis(1,10-phenanthroline)magnesium dichromate(VI) 1,10-phenanthroline disolvate

摘要

In the title compound, [Mg(C12H8N2)2(H2O)2][Cr2O7]·2C12H8N2, the cation and anion are situated on a twofold rotation axis. The MgII ion is coordinated by four N atoms from two 1,10-phenanthroline ligands and two O atoms from coordinated water mol­ecules in a distorted octa­hedral geometry. Inter­molecular O—H⋯N and O—H⋯O hydrogen bonds and π–π inter­actions between the aromatic rings [shortest centroid–centroid separation = 3.527 (2) Å] link the cations, anions and 1,10-phenanthroline solvent mol­ecules into a hydrogen-bonded cluster.
