dc.description.abstract | The title compound, {[CoLi2(C11H14N2O8) (H2O)3]·2H2O}n , constitutes the first example of a salt of the [M II(1,3-pdta)]2- complex (1,3-pdta is propane-1,3-diyldinitrilo-tetra-acetate) with a monopositive cation as counter-ion. Insertion of the Li+ cation could only be achieved through application of the ion-exchange column technique which, however, appeared unsuccessful with other alkali metals and the ammonium cation. The structure contains two tetra-hedrally coordinated Li+ cations, an octa-hedral [Co(1,3-pdta)]2- anion and five water mol-ecules, two of which are uncoordinated, and is built of two-dimensional layers extending parallel to the (010) lattice plane, the constituents of which are connected by the coordinate bonds. O - Hwater⋯O hydrogen bonds operate both within and between these layers. The crystal investigated belongs to the enanti-omeric space group P21 with only one () of two possible optical isomers of the [Co(1,3-pdta)]2- complex. A possible cause of enanti-omer separation during crystallization might be the rigidification and polarization of the [M(1,3-pdta)]2- core, resulting from direct coordination of Li + cations to three out of four carboxyl-ate groups constituting the 1,3-pdta ligand. The structure of (I) differs considerably from those of the other [M II(1,3-pdta)]2- complexes, in which the charge compensation is realized by means of divalent hexa-aqua complex cations. This finding demonstrates a significant structure-determining role of the counter-ions. | en |
