A novel two-dimensional network self-assembled by the narrowest ladder cations [Cu(CH_3COO)(bpe)(H_2O)]_n~(n+) containing the Cu_2(mu-O)_2 cores and the dimeric anions [Cu_2(nta)_2(bpe)]~(2-) through hydrogen-bonding interaction

摘要

A novel complex [Cu(CH_3COO)(bpe)(H_2O)]_n·n/2[Cu_2(nta)_2(bpe)]·6nH_2O (bpe = trans-1,2-bis (4-pyridyl) ethylene) was synthesized and characterized. The molecule structure shows that it is composed of the ladder-like double chain cations [Cu(CH_3COO)(bpe)(H_2O)]_n~(n+) and the dimeric anions [Cu_2(nta)_2(bpe)]~(2-). Through bridging oxygen atom of the acetate, the Cu_2(mu-O)_2 core is formed. The ladder-like chain cation is the narrowest ladder [3.422(3) A]. Two-dimenhsional undulating network is constructed by the cations and the dimeric anions through hydrogen-bonding interactions.
