trigonal prismatic complex

The (13)C NMR spectra of the metal complexes indicate that their structures are preserved at 20 degrees C in solution. The structural change is induced by bridging of the metal ions by a hydroxide ion (see below). Single-molecule magnets (SMMs) with one transition-metal ion often rely on unusual geometry as a source of magnetically anisotropic ground state. The Crystal and Molecular Structure of Tris(cis-l,2-diphenylethene-l,2-dithiolato)Rhenium. Show activity on this post. Magnetic blocking in a linear iron(I) complex. The Crystal and Molecular Structure of Tris(cis-l,2-diphenylethene-l,2-dithiolato)Rhenium. The naming system for these isomers depends upon the number and arrangement of different ligands. Author information: (1)Université Paris-Sud, UMR 8000, Orsay, 91405, France. Trigonal Prismatic Tris-pyridineoximate Transition Metal Complexes: A Cobalt(II) Compound with High Magnetic Anisotropy. The obtained zero-field splitting, which is also directly accessed by THz-EPR spectroscopy (-102.5 cm-1 ), results in a large magnetization reversal barrier U of 205 cm-1 . Trigonal prismatic at pH 4, octahedral at pH 6.5! A capped trigonal prismatic cadmium complex with tetra- and tridentate ligands: bis(triethanolamine In chemistry, the trigonal prismatic molecular geometry describes the shape of compounds where six atoms, groups of atoms, or ligands are arranged around a central atom, defining the vertices of a triangular prism. A Trigonal Prismatic Cobalt(II) Complex as a Single Molecule Magnet with a Reduced Contribution from Quantum Tunneling. Say you put a ligand in the trigonal complex (or an equatorial ligand in a trigonal bipyramidal complex) on the x -axis, where z is the "axial" axis. The central Cu(II) or Ag(I) atom is linked to two [NiL3a] ligands by oxamido bridges forming a trinuclear structure. AB - The crystal and molecular structure of tris(cis-1,2-diphenylethene-1,2-dithiolato)rhenium, Re(S2C2(C6H5)2)3, has been determined from three-dimensional X-ray data. The obtained zero-field splitting, which is also directly accessed by THz-EPR spectroscopy (-102.5 cm(-1)), results in a large magnetization reversal barrier U of 205 cm(-1). The Sm(III) is coordinatively saturated by the coordination of six oxygen atoms from dbm units and two pyridyl and one triazine nitrogen atoms from … Here we report a cobalt(II) cage complex with a…. The crystal structure consists of the packing of discrete monomeric molecules, the closest Re-Re distance being approximately 9.5 A. The phenyl rings are twisted out of the planes of the five-membered chelate rings and appear not to be conjugated with them. The trigonal prismatic coordination provided by the macrocyclic ligand gives intrinsically more stable molecular species than previously reported SMMs, thus making this type of cage complexes more amendable to possible functionalization that will boost their magnetic anisotropy even further. The sides of the prism are near perfect squares with an average edge of 3.043 A. While no crystallographic symmetry conditions are imposed on the molecule, the coordination geometry is clearly Dsh and the over-all molecular symmetry belongs nearly to the point group C3. The Crystal and Molecular Structure of Tris(cis-l,2-diphenylethene-l,2-dithiolato)Rhenium. The obtained zero‐field splitting, which is also directly accessed by THz‐EPR spectroscopy (−102.5 cm −1), results in a large magnetization reversal barrier U of 205 cm −1.
