✦ Synopsis

Aqua magnesium phthalocyanine bis(diethylamine) complex was obtained in the crystalline form and its crystal structure was determined by single-crystal X-ray diffraction. The Mg atom is 4 + 1 coordinated by four N isoindole atoms and one O atom. The MgPc moiety is non-planar, the Mg(II) is deviated by 0.492(2) A ˚from the N 4 -isoindole plane towards the oxygen atom of water molecule. The arrangement of MgPc(H 2 O) and diethylamine molecules is determined by O-HÁ Á ÁN hydrogen bonds and p-p interactions. The complex is stable up to $140 °C. At this temperature the complex loses diethylamine molecules and next at $200 °C loses the water molecule and finally converts into b-MgPc.
