A novel Eu(III)–Ag(I) heterometallic coordination polymer based on planar hexanuclear heterometallic second building unit

A novel Eu(III)–Ag(I) coordination polymer [Eu2Ag(μ4-oPyIDC)2(NO3)(H2O)]n (H3oPyIDC=2-(pyridine-3-yl)-1H-imidzole-4,5-dicarboxylate, 1) was formed based on a planar hexanuclear heterometallic Eu4Ag2 secondary building unit. The planar hexanuclear secondary building blocks are interconnected to a 3D framework with pcu topology. The luminescence property of compound 1 is also investigated.
