Abstract
An NiII coordination polymer, namely, poly[(μ2-adamantane-1,3-di-carboxyl-ato-κ4 O 1,O 1':O 3,O 3')[μ2-1,4-bis-(2-methyl-imidazol-1-ylmeth-yl)benzene-κ2 N 3:N 3']nickel(II)], [Ni(C12H14O4)(C16H18N4)]n or [Ni(adc)(bmib)]n, (I) [adc = adamantane-1,3-di-carboxyl-ate, C12H14O4 2- and bmib = 1,4-bis-(2-methyl-imidazol-1-ylmeth-yl)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.
