    • Single crystals of 1 (colourless parallelepipeds, 2 (green parallelepipeds, or 3 (orange-brown parallelepipeds) have been obtained by slow evaporation of equimolar aqueous solutions of MCl2 (M, Mg2+ or Ni2, and 1-Mecyt. Compounds 2 and 3 have been obtained in the Ni2+ solution as a mixture. Yields: 70, 1) and 75% for 2 and 3 (ca. 35 and 40% for 2 and 3, respectively, When crystals of compound 2 are allowed to stand in air for 1 week, a solid transformation accompanied by a color change from green to brown and a loss of crystallinity occurs, leading to a brown powder.
