Abstract :
A novel coordination polymer, [(NA)(ONA) Mn(II)]n (HNA = nicotinic acid; H2ONA = 2-hydroxynicotinic acid) has been hydrothermally synthesized. Its structure is constructed by mixed-ligands and chains of hexa-coordinated Mn(II) linkers: ONA groups bridge Mn ions to give the right-handed and left-handed helical [(ONA)Mn]n chains running along (010). The helical chains are further held together by NA groups to form a novel 3-D framework.
