Bis(ethylenediamine-N,N′)(pyrimidine-2-carboxylato-N¹,O)cobalt(III) bis(trifluoromethanesulfonate) dihydrate

Abstract

In the title compound, the coordination geometry of the CoIII atom is only slightly distorted from regular octahedral, and the racemic nature of the material was confirmed by X‐ray structure analysis.

Bis(pyrimidine-2-carboxylato-κ2N,O)copper(II)

“…The Cu II is located an inversion center and chelated by two pyrimidine-2-carboxylate anions in a CuO 2 N 2 square-planar coordination geometry ( Table 1). The pyridine-2carboxylate anion does not play a role of bridging ligand, this is different from the situation found in pyrimidine-2carboxylate complex of cobalt(II) and pyrimidine-2-carboxylate complex of iron(II) (Rodriquez-Dieguez et al, 2007), but similar to that found in pyrimidine-2-carboxylate complex of cobalt(III) (Antolić et al, 2000). In the title crystal, two carboxylate-O atoms from adjacent molecules occupy at the axial direction of the Cu II ion (Fig.…”
