A 2-D polymer constructed through bridging acetate, hydroxo, aqua and bipyridine ligands: crystal structure of {[Cu2(μ-CH3COO)(μ-OH)(μ-H2O)(4,4′-bipy)](2H2O)(SiF6)}n

A novel 2-D coordination polymer constructed by μ2-acetate-O,O′, μ2-hydroxo, μ2-aqua and 4,4′-bipyridine (bipy) ligands has been synthesized and structurally characterized. Linear 1-D chain built by bridged μ2-acetate-O,O′, μ2-hydroxo and μ2-aqua units is composed of Cu2O2 motifs and syn-anti bridged acetate ligands. The copper atom with a five-coordination has a distorted square-pyramidal geometry completed by two nitrogen atoms from 4,4′-bipyridine and three oxygen atoms from acetate, hydroxo and water ligands. The strong stacking effect is observed between 4,4′-bipyridine ligands.
