摘 要: | The title coordination polymer including two crystallographically independent Co2+ ions is hydrothermally synthesized, in which the Co(1) 2+ ion is four-coordinated by two carboxylate oxygen atoms from two different 5-(benzoic acid-4-yldiazenyl)isophthalate (byip3-) anions and two nitrogen atoms from two distinct 1,4-bis(imidazol-1-ylmethyl) benzene (bix) ligands displaying a tetrahedral geometry. The Co(2) 2+ ion is six-coordinated by two water molecules at the apical positions, and two carboxylate oxygen atoms and two nitrogen atoms at the equatorial positions, affording a slightly distorted octahedron. Two Co(1)2+ and two Co(2)2+ ions are linked together by four byip3- anions forming a 44-membered motif and these motifs are further arranged into a three-dimensional framework through bix ligands along the a axis with a larger channel (ca. 22.70×11.01). Each individual network interpenetrates with the other identical network in a parallel fashion to generate a 2-fold interpenetrating array with the {62.84}{63}2{64.82}2 topology.
