Two new neutral polymeric layer compounds, [Cu 3 (bpy) 2 (Hip) 2 (ip) 2 ] ( 1 ) and [Cu 3 (phen) 2 (Hip) 2 (ip) 2 ] ( 2 ) (bpy = 2, 2′‐bipyridine, phen = 1, 10‐phenanthroline, ip = isophthalate), have been synthesized under hydrothermal conditions and characterized by X‐ray crystallography. Complex 1 crystallizes triclinic, P 1¯ (No. 2), a = 10.352(5), b = 10.859(6), c = 11.602(6)Å, α = 83.25(1), β = 84.71(1), γ = 66.19(1)°, V = 1183.5(11)Å 3 , Z = 1; 2 triclinic, P 1¯ (No. 2), a = 10.375(1), b = 10.668(1), c = 11.758(1)Å, α = 83.179(2), β = 86.228(2), γ = 71.187(2)°, V = 1222.7(2)Å 3 , Z = 1. The complexes consist of trinuclcear copper units that are bridged via two ip ligands forming zigzag polymeric chains. These chains are further extended into layers via aromatic π‐π interactions as well as hydrogen bonds between the free carboxyl groups and carboxylates.
