The analysis of Mn-chalcogen bond length and of tetrahedral covalent radius of Mn (r(tc)(Mn)) in A -NIn,13"' and in Mn chalcogenides, performed in the previous paper [Chem. Phys. Lett. 350 (2001) 577], was supplemented here by the case of A(1-x)(III)Mn(x)B(v) (A(III) = In, Ga; B-v = As, N) compounds. It was found that for chalcogen anions the dependence of r(tc)(Mn) vs anion atomic number (A(a) can be linearly approximated. Inclusion of the respective values for the group-V anions (As, N) reveals their consistency with the above r(tc)(Mn)(A(a)) dependence thus suggesting its more 'universal' character.
