A　europium　complex　[Eu-2(bmd)(2)(Hbmd)(2)(H2O)(8)]　center　dot　8H(2)O　(H(2)bmd=Benzimidazole-5,6-dicarboxylic　acid)　has　been　synthesized　and　structurally　determined　by　X-ray　diffraction　single　crystal　structure　analysis.　The　crystal　belongs　to　triclinic,　space　grounp　P　(1)　over　bar,　with　a=0.754　49(15)　nm,　b=1.253　8(3)　run,　c=1.405　8(3)　nm,　alpha=71.03(3)degrees,　beta=82.83(3)degrees,　gamma=79.12(3)degrees,　V=1.232　1(5)　nm(3),　Z=1.　The　complex　is　a　binuclear　compound　and　each　E(III)　ion　is　nine-coordinated.　The　versatile　hydrogen　bonds　link　binuclear　units　into　a　three-dimensional　(3D)　supermolecular　network.　Furthermore,　the　fluorescent　properties　of　the　complex　have　been　investigated　at　room　temperature.　CCDC:　742510.
