Three
new heterometallic formate coordination polymers formulated as [Na2Co(HCOO)4]∞ (1),
[NaCo(HCOO)3]∞ (2), and
[Na2Co7(HCOO)16]∞ (3) were obtained by adjusting the solvent and ratio
of the reactants. In 1, a (4,4) cobalt formate layer
is formed and the sodium ions connect the layers to form a three-dimensional
(3D) framework. In 2, each formate ligand binds two Co2+ and two Na+ ions with a syn,syn,anti,anti coordination
mode to form a chrial network with 4,6-connected topology. 3 is a Na+-ion-linked 3D framework based on the cobalt
formate layer, which has a 10-membered metal ring. Magnetic studies
indicate the existence of ferromagnetic interactions between adjacent
Co2+ ions in 1, while dominating antiferromagnetic
couplings in 2 and 3.
