In the title compound, [NdCl(3)(C(12)H(10)N(2)O)(3)], the central Nd(III) ion is nine-coordinated by six N atoms from three bidentate chelate N-[phen-yl(pyridin-2-yl)methyl-idene]hydroxyl-amine ligands and three Cl(-) ions, and displays a distorted tricapped trigonal prismatic geometry. The complex mol-ecules are stabilized by intra-molecular O-H⋯Cl hydrogen bonds.

X- and Q-band EPR and ENDOR spectroscopy was used to study the structure of a series of heteroleptic and homoleptic copper bis(oxazoline) complexes, based on the (-)-2,2'-isopropylidenebis[(4S)-4-phenyl-2-oxazoline] ligand and bearing different counterions (chloride versus triflate); labelled [Cu(II)(1a-c)]. The geometry of the two heteroleptic complexes, [Cu(II)(1a)] and [Cu(II)(1c)], depended...

The title compound, [Cu(2){SC(NH(2))NHNH(2)}(6)]I(2), was obtained by the reaction of CuI and thio-semicarbazide (TSCZ) in acetonitrile. Each Cu(I) ion is coordinated by four S atoms of the TSCZ ligands, forming a tetra-hedral geometry. Centrosymmetric dimers are formed by two coordination tetra-hedra sharing a common edge, with a Cu⋯Cu distance of 2.8236 (14) Å. The I(-) ion does not have any ...

Ab initio calculations show that a possible mechanism for the photomagnetism in copper octacyanomolybdate compounds consists of the initial excitation of the diamagnetic Cu(II)-Mo(IV-CS) pair to a Cu(II)-Mo(IV-T) state, whose geometry relaxation stabilizes the magnetic doublet and quartet states.

The transition from low to high density 2D surface structures of copper porphyrins at a liquid/solid interface requires specific defects at which nearly all exchange of physisorbed molecules with those dissolved in the supernatant occurs.

Asymmetric allylic amination or oxidation can be achieved by reaction of an alkene with a peroxycarbamate catalysed by a chiral copper bis-oxazoline complex, and the reaction can be tuned to give either the amination or oxidation product by reagent choice.

The enantioselective, intermolecular hydroallylation of vinylarenes employing allylic phosphate electrophiles has been achieved through a copper hydride catalyzed process. The protocol described herein can be applied to a diverse set of vinylarene substrates and allows for the installation of the parent allyl group as well as a range of 2-substituted allylic fragments.

Mono-, di-, and trinuclear copper-azido moieties have been synthesized by varying the size of the countercations. [Bu4N]+ yielded a [Cu2(N3)6]2- copper-azido moiety in [Bu4N]2[Cu2(mu(1,1)-N3)2(N3)4], 1, and [Pr4N]+ yielded a [Cu3(N3)8]2- moiety in {[Pr4N]2[Cu3(mu(1,1)-N3)4(N3)4]}n, 2, in which symmetry-related [Cu3(N3)8]2- moieties are doubly mu(1,1)-azido bridged to form unprecedented infinite...
