Two new supermolecular structures of organic-inorganic hybrid compounds: [Zn(phen)(SO4)(H2O)2]n and [Cu(phen)(H2O)2] · SO4 (phen = 1,10-phenanthroline)

In this paper, two organic-inorganic hybrid compounds containing SO42− anion and phen moiety supramolecular complexes have been synthesized and characterized for the first time. The SO42− groups in complexes 1 and 2 are used as counter anions. But the SO42− anion in 1 adopts bidentate mode to coordinate with metal ions and the complex displays one-dimensional polymer. In the case of 2, the uncoordinated SO42− groups are presented. Such effects of the counter anions may provide the prospect of synthesizing new organic-inorganic hybrid transition metal supramolecular complexes by the modification of inorganic ligands and the organic ligands. The two compounds exhibit a broad fluorescent emission bands, and it maybe can use as fluorescent materials. It is believed that more and more hybrid compounds with good luminescent property can be developed.
