Poly[(μ(3)-5-amino-isophthalato-κO,O':O'':O''')[μ(2)-1,2-bis-(4-pyrid-yl)ethane-κN:N']cobalt(II)].

ABSTRACT: In the title compound, [Co(C(8)H(5)NO(4))(C(12)H(12)N(2))](n), the Co(II) ion presents a distorted CoO(4)N(2) octa-hedral coordination geometry, formed by three 5-amino-isophthalate dianions and two 1,2-bis-(4-pyrid-yl)ethane ligands. One carboxyl-ate group of the 5-amino-isophthalate dianion chelates a Co cation and the other carboxyl-ate group bridges the other two Co cations, while the terminal N atoms of the 1,2-bis-(4-pyrid-yl)ethane ligand coordinate the neighboring Co cations, forming a two-dimensional polymeric architecture. Two pyridine rings of the 1,2-bis-(4-pyrid-yl)ethane ligand are twisted to each other with a dihedral angle of 50.94 (16)°. Weak C-H⋯O hydrogen bonding and N-H⋯π inter-actions are observed in the crystal structure. A void of 69 (5) Å(3) is present in the crysta
