✦ Synopsis

The synthesis, properties and X-ray crystal structure of

[Ni(Me3112]N3)(O2N)(H20)](ClO4).2H20, in which

Me3[12]N 3 is 2,4,4-trimethyl-l,J,9-triazacyclododec-1ene, are described. The Ni atom is octahedrally coordinated to three N atoms of the macrocycle, two O atoms of the nitrito group and one H20 molecule. Monomeric units are linked by hydrogen bonds through one of the water of crystallization molecules, forming a chain. Magnetic measurements between 290 and 4 K reveal slight antiferromagnetic behaviour.
