Some ruthenium(III) complexes of the type trans-[Ru(L)X₂]⁺ with four different saturated macrocyclic quadridentate secondary amines [L = 1,4,8,11-tetraazacyclotetradecane (cyclam), X₂ = (Cl)Br, I₂, (NCS)₂, and (CH₃COO)₂; L = 1,4,8,12-tetraazacyclopentadecane ([15]aneN₄), C-meso- and C-rac-5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane (teta and tetb respectively), X₂ = Cl₂ and Br₂] have been prepared and characterized. They are all monomeric, low-spin species with a trans configuration. The electronic and infrared absorption spectra of these complexes are discussed.
