Abstract
The heats of formation of 1:1 and 1:2 complexes of Ni2+ and Cu2+ with the ligand 1,3,5-cis,cis-triaminocyclohexane [26150-46-9] were detd. in aq. soln. by microcalorimetric methods. The corresponding entropy values were obtained by combination with literature free energy values. Comparison with data for the coordination of more flexible triamines emphasizes the role of the rigidity of the ligand
