One three-dimensional Sr(II) coordination polymer [C6(MIm)2][Sr3(1,4-NDC)4] (I) (C6(MIm)2 = 1,3-bis(3-methylimidazolium-1-yl)hexyl, 1,4-H2NDC = 1,4-naphthalenedicarboxylate acid) has been synthesized using an ionothermal method and structurally characterized by IR spectroscopy, UV-Vis spectroscopy, XRPD, and X-ray single-crystal structure analysis (СIF file CCDC 1033958). Two types of strontium centers are bridged by two coordination modes of 1,4-H2NDC ligands to form a Sr(II) chain. Each Sr(II) chain is crossconnected to four other chains to generate a 3D coordination polymer, in which C6(MIm)22+ cations as charge balancing species are filled in the channels of the anionic framework. The polymeric solid of I exhibits strong luminescent emission at room temperature.
