Two novel copper(II) coordination polymers, [CuNa 2 (Hnta) 2 ] n ( 1 ) and {[CuNa 2 (pht) 2 (H 2 O)]·H 2 O} n ( 2 ) (H 3 nta = nitrilotriacetate acid, H 2 pht = o ‐phthalic acid), have been synthesized and characterized.The sodium ions play an important role in the formation of the multi‐dimensional structures. The X‐ray structure of [CuNa 2 (Hnta) 2 ] n ( 1 ) is three‐dimensionally cross‐linked with building blocks [Cu(Hnta) 2 ] 2— connected by three sodium ions. The structure of {[CuNa 2 (pht) 2 (H 2 O)]·H 2 O} n ( 2 ) can be described as pht units connected by Na ions via Na—O bonds to form chains, which are linked by Cu II ions to make a 2D network. The IR spectra and thermal properties are also reported.
