Hydrothermal Synthesis and Structure of Two 1-D Organic Hybrid Metal Sulfates

Two new complex copper(II) sulfates [Cu(1,10-phen)(H2O)2]SO4 (1, 1,10-phen = 1,10-phenanthroline) and [Cu(2,2′-bipy)(H2O)2]SO4 (2, 2,2′-bipy = 2,2′-bipyridine) have been hydrothermally synthesized and characterized by IR spectroscopy, elemental analysis, thermogravimetric analysis, and X-ray crystallography. 1 and 2 consist of complex cations [Cu(1,10-phen/2,2′-bipy)(H2O)2]2+ and SO42− anions, which are interconnected via weak Cu· · ·O interactions to form rare examples of 1-D metal sulfates.
