Poly[[μ-1,3-bis-(pyridin-3-yl)urea]bis-(μ(4)-glutarato)dicopper(II)].

The title compound, [Cu(2)(C(5)H(6)O(4))(2)(C(11)H(10)N(4)O)](n), contains square-pyramidally coordinated Cu(II) ions linked by anti-gauche conformation glutarate (glu) ligands into [Cu(2)(glu)(2)](n) di-periodic coordination polymer layers with embedded [Cu(2)(OCO)(4)] paddlewheel clusters. In turn, the layer motifs are connected by 1,3-di(pyridin-3-yl)urea (3-dpu) linkers to form a [Cu(2)(glu)(2)(3-dpu)](n) tri-periodic coordination polymer network. Treating the [Cu(2)(OCO)(4)] clusters as 6-connected nodes reveals an underlying 4(12)6(3) pcu topology according to TOPOSPRO software [Blatov et al. (2014 ▸). Cryst. Growth Des. 14, 3576-3586].
