Crystal structure and luminescence spectrum of a one-dimensional nickel(II) coordination polymer incorporating 1,4-bis[(2-methylimidazol-1-yl)methyl]benzene and adamantane-1,3-dicarboxylate co-ligands

An NiII coordination polymer, namely, poly[( μ 2-adamantane-1,3-dicarboxylato- κ 4O1,O1 ′ :O3,O3 ′ )[ μ 2-1,4-bis(2-methyl-imidazol-1-ylmethyl)benzene- κ 2N3:N3 ′ ]nickel(II)], [Ni(C12H14O4)(C16H18N4)]n or [Ni(adc)(bmib)]n, (I) [adc = adamantane-1,3-dicarboxylate, C12H14O42 – and bmib = 1,4-bis(2-methyl-imidazol-1-ylmethyl)benzene, C16H18N4] was synthesized and characterized. It exhibits a one-dimensional extended structure built up from alternating [Ni2(bmib)2] 26-membered rings and [Ni2(adc)2] 16-membered rings. The nickel atom lies on a crystallographic twofold axis and both ligands are completed by mirror symmetry. The solid-state luminescence spectra of (I) and the bmib ligand show strong emissions at 442 and 410   nm, respectively.
