A new 3d-4f polymer formulated as {[Sm Co2(μ2-Hmimda)3(μ2-H2mimda)·4H2O]· 3H2O}n(H3mimda = 1-H-2-methyl-4,5-imidazole-dicarboxylic acid) has been hydrothermally synthesized and structurally characterized by elemental analysis,X-ray single-crystal diffraction and magnetic susceptibility measurement.It crystallizes in monoclinic system,space group C2/c,with a = 17.251(6),b = 16.965(6),c = 14.668(5) ?,β = 118.565(5)?,Z = 4,V = 3770(2) ?3,F(000) = 1984,the final R = 0.0597 and w R = 0.1820.In the crystal,the dicarboxylate ligand links the Sm(ⅡI) and Co(Ⅱ) ions to give rise to a heterometallic [Sm Co2(μ2-Hmimda)3(μ2-H2mimda)] aggregate which acts as the second building unit.Then,the SBUs further extended a 2D corrugated layer with a(4,4) topology.The title complex displays strong photoluminescence in the solid state.

It crystallizes in monoclinic system, space group C2 / c, with a = 17.251 (6), b = 16.965 the final R = 0.0597 and w R = 0.1820. In the crystal (c = 14.668 (5) ?,? = 118.565 (5) ?, Z = 4, V = 3770 , the dicarboxylate ligand links the Sm (ⅡI) and Co (Ⅱ) ions to give rise to a heterometallic [Sm Co2 (μ2-Hmimda) 3 (μ2-H2mimda)] aggregate which acts as the second building unit. further extended a 2D corrugated layer with a (4,4) topology.The title complex displays strong photoluminescence in the solid state.
