摘要：

In the title compound, [Mg(C44H28N4)(H2O)(2)]center dot C12H24O6, the Mg II cation lies on an inversion center and is octahedrally coordinated by the four N atoms of the deprotonated tetraphenylporphyrin (TPP) ligand and by two water molecules. The asymmetric unit contains one half of the [Mg(TPP)(H2O)(2)] complex and one half of an 18-crown-6 molecule. The average equatorial magnesium-pyrrole N atom distance (Mg-Np) is 2.071 (1)angstrom and the axial Mg-O(H2O) bond length is 2.213 (1)angstrom. The crystal packing is stabilized by two O-H center dot center dot center dot O hydrogen bonds between coordinating water molecules and adjacent 18-crown-6 molecules, and exhibits a one-dimensional supramolecular structure along the a axis. The supramolecular architecture is futher stabilized by weak C-H center dot center dot center dot pi interactions. The 18-crown-6 molecule is disordered over two sets of sites with an occupancy ratio of 0.8: 0.2.
