Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. In an article, published in an article, once mentioned the application of 499-40-1, Name is (2R,3S,4R,5R)-2,3,4,5-Tetrahydroxy-6-(((2S,3R,4S,5S,6R)-3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)hexanal,molecular formula is C12H22O11, is a conventional compound. this article was the specific content is as follows.Reference of 499-40-1
The synthesis and crystal structure of two heteronuclear compounds stabilized by four dipyridylamide (dpa) ligands is reported. Cu 2Pd(dpa)4Cl2 (1) and Cu2Pt(dpa) 4Cl2 (2) exhibit an approximate D4 symmetry and a linear metal framework. They are structurally similar to the homotrinuclear complexes M3(dpa)4L2 already characterized with various transition metals (M = Cr, Co, Ni, Cu, Rh, Ru). With 26 metal valence electrons, they are also isoelectronic to the oxidized form of the tricopper complex [Cu3(dpa)4Cl2]+ (3), previously characterized and investigated by Berry et al.10 The magnetic properties and the EPR spectra of 1 and 2 are reported. The results for 1 are interpreted in terms of a weak antiferromagnetic interaction (2J = 7.45 cm-1 within the framework of the Heisenberg Hamiltonian H = -2JAB SASB) between the Cu(II) magnetic centers. For 2, the antiferromagnetic interaction sharply decreases to <1 cm-1. These properties are at variance with those of (3), for which a relatively strong antiferromagnetic interaction (2J = -34 cm -1) had been reported. DFT/UB3LYP calculations reproduce the decrease of the magnetic interaction from 3 to 1 and assign it to the role of the nonmagnetic metal in the transference of the superexchange coupling. However, the vanishing of the magnetic interaction in 2 could not be reproduced at this level of theory and is tentatively assigned to spin-orbit coupling. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 499-40-1, help many people in the next few years., Reference of 499-40-1
