Bis-ligand cobalt(II) complexes of 2,4,6-tris(2-pyridyl)-1,3,5-triazine and 2,3,5,6.tetrakis(2-pyridyl)pyrazine have been prepared. The conductivities of the complexes in nitromethane solution correspond to values expected for bi-unielectrolytes. The temperature dependence of their magnetism has shown that in some instances there exists a spin-state equilibrium in the metal atom while in others the metal atom is spin-free and Curie-Weiss laws are obeyed.

Mono and bis iron(11) complexes of 2,4-bis(2-pyridyl)thiazole have been described. Conductivity and visible and infrared spectral data suggest that the mono complexes are five-coordinate. The magnetism of the bis complexes, in contrast to that of the mono complexes, shows unusual temperature dependence. This has been ascribed to the presence, in the bis complexes, of a spin-state equilibrium. Bis[2,4-bis(2-pyridyl)thiazole]cobalt(11) perchlorate has been shown to be a simple paramagnetic compound.
