Synthesis, vibrational spectra, and crystal and molecular structure of copper 1,5-bis[2-(dihydroxyphosphinyl)phenoxy]-3-oxapentane dihydrate [Cu(H2L2)(H2O)2]
摘要:
A new complex Cu(H2L2)(H2O)(2)] (I), where H4L2 is 1,5-bis[2-(dihydroxyphosphinyl)phenoxy]-3-oxapentane, has been synthesized and characterized. Its molecular and crystal structure has been determined by X-ray crystallography and vibrational spectroscopy. In mononuclear complex I, the copper(II) cation is in a distorted square-planar environment of two water oxygen atoms and two oxygen atoms of the chelating dianion (H2L2)(2-). The crystals are orthorhombic, space group Cmc2(1), a = 25.909(5) , b = 9.1500(18) , c = 8.5600(17) , V = 2029.3(7) (3), Z = 4, rho(calc) = 1.688 g cm(-3), mu = 1.292 cm(-1); 3107 measured reflections, 1174 reflections with I > 2.0 sigma(I), R (int) = 0.0600, GOOF = 1.413, R (1) (I > 2 sigma(I)) = 0.0812, wR (2) (I > 2 sigma(I)) = 0.2145.
