abstract

  • The reaction of 1,4,8,11-tetrakis(3-hydroxy-6-methyl-2-pyridylmethyl)-1,4, 8,11- tetraazacyclotetradecane with nickel and cobalt nitrate in methanol at 1: 1 molar ratio afforded two new crystals. Both of them are isotructural analogues. Nickel complex crystallized in triclinic space group P-1 with a=10.050(3), b=12.599(4), c=18.267(6) , =109.595(3), =103.829(7), =93.376(6), V=2091.2(12) 3, and Z=2. The Ni(II) ions are five-coordinated by four nitrogen atoms and one phenolic oxygen atom. Their coordination geometry can be described as square pyramid, with short Ni-O distance.(1.984(3)) Cobalt complex crystallized in triclinic space group P-1 with a=9.9479(9), b=12.4441(11), c=18.2620(16) , =108.0730(10), =104.5780(10), =93.2030(10), V=2057.8(3) 3, and Z=4. The Co(II) ions are also five-coordinated by similar atoms as found in copper complex. 2003 Published by Elsevier B.V.
