A microcalorimetric determination of the enthalpies of formation in solution of nickel (II) complexes with tetraaza macrocyclic ligands of varying size
The enthalpies of formation of nickel complexes with tetraaza macrocyclic ligands of varying ring size, from 12 to 15 members, have been determined by destroying the complexes in aqueous solution with alkaline cyanide. The octahedral-square-planar equilibria have been investigated, and the results are presented as AHo for both octahedral, blue and, when possible, square-planar, yellow species. Like the Cu (I1) system, the blue, octahedral ...
