Aqua(phthalocyaninato)magnesium n-propylamine disolvate.

The crystals of the title compound, [Mg(C(32)H(16)N(8))(H(2)O)].2C(3)H(9)N, are built up from MgPc(H(2)O) [Pc is phthalocyaninate(2-)] and n-propylamine molecules that interact via O-H...N hydrogen bonds. The MgPc(H(2)O) 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) A from the N(4) plane towards the water O atom. MgPc(H(2)O).2(n-propylamine) molecules related by the inversion centre are linked by N-H...O hydrogen bonds to form a dimeric aggregate.
