Aqua­(phthalocyaninato)magnesium n-propyl­amine disolvate

The crystals of the title compound, [Mg(C₃₂H₁₆N₈)(H₂O)]·2C₃H₉N, are built up from MgPc(H₂O) [Pc is phthalo­cyaninate(2−)] and n-propyl­amine mol­ecules that inter­act via O—H...N hydrogen bonds. The MgPc(H₂O) mol­ecule is non-planar. The central Mg atom is coordinated by the four equatorial isoindole N atoms of the Pc ring system and by the O atom of an axial water mol­ecule. The Mg atom is displaced by 0.509 (1) Å from the N₄ plane towards the water O atom. MgPc(H₂O)·2(n-propyl­amine) mol­ecules related by the inversion centre are linked by N—H...O hydrogen bonds to form a dimeric aggregate.

Aqua­(phthalocyaninato-κ⁴N)­magnesium(II) 3-chloro­pyridine disolvate

The structure of the title compound, [Mg(C₃₂H₁₆N₈)(H₂O)]·2C₅H₄ClN, comprises MgPcH₂O [Pc is phthalocyaninate(2−)] and 3-chloro­pyridine solvent mol­ecules inter­acting via O—H...N hydrogen bonds and π–π inter­actions. The central Mg atom is (4+1)-coordinated by four equatorial isoindole N atoms of the macrocycle and by the O atom of an axial water mol­ecule. The MgPcH₂O mol­ecule is not planar, the Mg atom being displaced by 0.496 (2) Å from the isoindole N₄ plane towards the water O atom. MgPcH₂O mol­ecules related by a twofold screw axis inter­act via O—H...N_azamethine hydrogen bonds, forming a polymeric chain along the b axis, while those related by inversion centres form π–π inter­acting dimers.
