Poly[di-aqua-[μ-1,4-bis-(pyridin-3-ylmeth-yl)piperazine][μ-4-(2-carboxyl-atoeth-yl)benzoato]cobalt(II)].

A layered cobalt coordination polymer containing both 4-(2-carboxyl-atoeth-yl)benzoate (ceb) and 1,4-bis-(3-pyridyl-meth-yl)piperazine (3-bpmp) ligands, [Co(CHO)(CHN)(HO)] or [Co(ceb)(3-bpmp)(HO)] , was isolated and structurally characterized by single-crystal X-ray diffraction. Chain-like [Co(ceb)(HO)] units are oriented parallel to [101]. These are connected into (4,4)-grid coordination polymer layers by tethering 3-bpmp ligands.

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

The title compound, [Cu(CHO)(CHNO)], contains square-pyramidally coordinated Cu ions linked by conformation glutarate (glu) ligands into [Cu(glu)] di-periodic coordination polymer layers with embedded [Cu(OCO)] paddlewheel clusters. In turn, the layer motifs are connected by 1,3-di(pyridin-3-yl)urea (3-dpu) linkers to form a [Cu(glu)(3-dpu)] tri-periodic coordination polymer network. Treating the [Cu(OCO)] clusters as 6-connected nodes reveals an underlying 46 topology according to software [Blatov (2014 ▸).
