title: catena-Poly[[bis-[4-(dimethyl-amino)-pyridine-κN (1)]cobalt(II)]-di-μ-azido-κ(4) N (1):N (3)].
abstract: The title layered polymer, [Co(N3)2(C7H10N2)2] n , contains Co(II), azide and 4-(dimethyl-amino)-pyridine (4-DMAP) species with site symmetries m2m, 2 and m, respectively. The Co(2+) ion adopts an octa-hedral coordination geometry in which four N atoms from azide ligands lie in the equatorial plane and two 4-DMAP N atoms occupy the axial positions. The Co(II) atoms are connected by two bridging azide ligands, resulting in a chain parallel to the c axis.
