| Abstract: The title complex [Cu2(C4H2O6)(Phen)2(H2O)]·8H2O (where phen is 1,10-phenanthroline, C4H6O6 is tartaric acid) has been synthesized and characterized by X-ray single-crystal diffraction. It crystallizes in the monoclinic sys-tem, space group P21 with a=0.716 52(6) nm, b=2.205 44(17) nm, c=1.067 83(11) nm, β=102.595(5)°, V=1.646 8(3) nm3, Z=2, Dc=1.605 g·cm-3, Mr=795.69, μ(Mo Kα)=1.369 mm-1, F(000)=820, the final R=0.034 1 and wR=0.062 2 for 5 613 observed reflections[I>2σ(I)]. The complex is a binuclear copper compound, and the two Cu(II) atoms are in different coordination environments. The Cu(1) atom is five-coordinated with distorted square pyramid geometry, whereas the Cu(2) atom assumes the coordination geometry of a distorted square plane. The distance of Cu(1)…Cu(2) is 0.354 8 nm. In addition, there exist intramolecular π-π stacking interactions between two phen rings with the interplanar distance of 0.381 3 nm. The complex has a good effect against E. Coli, S. Aureus and B. Subtilis. CCDC: 634855. |
