N2  - (4,4,9,9-Tetramethyl-5,8-diazadodecane-2,11-dione dihydrazone)nickel(II) perchlorate reacts with 2- aminoethanol and methanal to form blue-violet (17-hydroxy-4,4,9,9,11-pentamethyl-5,8,12,13,15- pentaazaheptadec-11-en-2-one hydrazone)nickel(II) perchlorate. The structure of a methanol solvate was determined &#91;C18H43Cl2N7NiO10, Mr 647&#183;2, triclinic, space group P -1, a 8&#183;992(7), b 10&#183;86(2), c 15&#183;02(1) &#197;, &#945; 79&#183;95(2), &#946; 76&#183;85(5), &#947; 78&#183;83(2)&#176;, Z 2, R 0&#183;0637 for 2992 reflections&#93;. The ligand has one terminal hydrazone function of the starting material linked to the 2-aminoethanol residue by a gem-diamine function derived from methanal. The ligand is hexadentate, with the triplet ground state nickel(II) ion in octahedral coordination by three secondary amine and two hydrazone nitrogen atoms and a hydroxy oxygen atom, with the terminal hydrazone nitrogen and the hydroxy oxygen atoms coordinated trans.
