A high-connected self-penetrating network supported by pentanuclear cobalt(II) secondary building units

A 3D ten-connected self-penetrating network based on the pentacobalt(II) clusters, [Co5(1,4-ndc)4(OH)2(1,3-bix)2]n (1) (1,4-H2ndc = 1,4-naphthalenedicarboxylic acid; 1,3-bix = 1,3-bis(imidazol-1-ylmethyl)benzene), is synthesized and characterized. Topological analysis indicates that it has ile-364345362 network. The magnetic data reveals the dominant antiferromagnetic interactions between the Co(II) cations.
