The coordination spheres of the nickel and copper metal centers in the condensed phase are compared for a series of N-substituted β-alaninate ligands with the regularly changed dentate mode. In the case of the copper(II) complexes, an increase in the size of the alkanolamine chelate ring or the number of hydroxymethyl groups provides the formation of achiral coordination struc -tures, whereas the structures of the nickel(II) complexes are independent of the size of the lkanolamine che -late ring or the number of hydroxymethyl groups, thus providing the formation of the complexes as racemic modifications Доп.точки доступа: Pestov, A.
