A magnetic study of a series of dihydroxy-bridged copper compounds of 2,2'-bipyridyl and 1,10-phenanthroline

Abstract

The magnetic susceptibility of the compounds [(amine)Cu(OH)]₂X₂,nH_2O, where amine = 2,2'-bipyridyl or 1,l0-phenanthroline; X = Cl, I, NCS, NCSe, or ½SO₄; and n varies from 5 to 1 depending on the complex, has been measured in the liquid nitrogen temperature range. The magnetic data are consistent with a triplet ground state for the sulphate and iodide salts.
