| Popis: | The synthesis, optical and magnetic properties and X-ray crystal structure of [Cu(2-aminopyrimidine)2(OH)(CF3SO3)]2(2aminopyrimidine)2, a new dinuclear hydroxo-bridged copper(II) compound with a CuOCu angle of 97.96° and a very small antiferromagnetic interaction for which the singlet–triplet exchange parameter J, is described. The magnetic exchange coupling is almost negligible and, depending on the actual sample, varies from − 1.8 to − 7.2 cm − 1 . © 2002 Published by Elsevier Science |
