Aqua­(phthalocyaninato)­magnesium

The title compound, Mg(C₃₂H₁₆N₈)(H₂O)], crystallizes with two MgPc(H₂O) mol­ecules (Pc is phthalocyaninate) in the asymmetric unit. The geometries of the two mol­ecules are very similar, with the Mg atoms each 4+1‐coordinated by four iso­indole N atoms at the base and by the O atom of the water mol­ecule. The Mg atoms are displaced by 0.447 (1) and 0.468 (1) Å from the basal coordination planes towards the water O atoms. O—H?N hydrogen bonds form dimers stacked along the b axis in a herring‐bone fashion.
