The relative stability of nano-“chromic wheels” [Crn(OCH3)2n(CH3COO)n] depending on the number of their coordination units

The relative stability of [Crn(OCH3)2n(CH3COO)n] depending on the number n (n = 4, 6, 8, 10, 12 and 14) of its interior groups is studied by means of Hartree-Fock and also Density Functional Theory calculations.
