Bis(3-amino-pyrazine-2-carboxyl-ato-?(2)N(1),O)diaqua-cobalt(II).

ABSTRACT: In the title compound, [Co(C(5)H(4)N(3)O(2))(2)(H(2)O)(2)], the Co(II) atom is situated on a twofold rotation axis and is N,O-chelated by two 3-amino-pyrazine-2-carboxyl-ate anions and additionally bonded to the O atoms of two water mol-ecules, leading to a slightly distorted octa-hedral coordination environment. The crystal packing is dominated by inter-molecular O-H?O, O-H?N and N-H?O hydrogen bonding involving the water mol-ecules and amino groups as donors and carboxyl-ate O atoms, as well as the non-coordinating heterocyclic N atoms as acceptors, resulting in a three-dimensional network. An intra-molecular N-H?O hydrogen bond is also observed.

Project description:The asymmetric unit of the polymeric title compound, {[Pr(2)(C(5)H(4)N(3)O(2))(5)(CHO(2))(H(2)O)(5)]·6H(2)O}(n), has two independent Pr(III) atoms; one is coordinated by two water mol-ecules and the other by three water mol-ecules. The first is N,O-chelated by three 3-amino-pyrazine-2-carboxyl-ate ions, whereas the second is chelated by two carboxyl-ate ions; both exist in a monocapped square-anti-prismatic geometry. The polymeric chains that run along the a axis inter-act with the lattice water mol-ecules, generating a three-dimensional hydrogen-bonded network. The formate ion is disordered over two positions with respect to the non-coordinated atoms in a 1:1 ratio.
