Laue's experiment in 1912 of the diffraction of X-rays by crystals led to one of the most influential discoveries in the history of science: the first determinations of crystal structures, NaCl and diamond in particular, by W. L. Bragg in 1913. For the fir ...
Homoleptic mononuclear nine-coordinate lanthanum(III) and europium(III) tris-complexes [Ln(N^N^O)3]·nH2O with two tridentate N-benzyl-benzimidazole pyridine-2-carboxylates exhibit a rare C3-symmetry of the lanthanide coordination polyhedron in the solid st ...
Two neutral and two cationic half-sandwich Os(II)-arene metallodendrimers, of general formula [DAB-PPI-{(eta(6)-p-cym)Os((C7H5NO)-kappa(2)-N,O)Cl}(n)] and [DAB-PPI-{(eta(6)-p-cym)Os((C6H5N2)-kappa(2)-N,N)Cl}(n)]PF6 (where n = 4 (G1) or 8 (G2)) have be ...
Enantioselective total syntheses of title natural products from a common cyclohexenone derivative (S)-18 were reported. Ozonolysis of (S)-18 afforded a stable diketo ester (R)-17 that was subsequently converted to two skeletally different natural products, ...
Described are the synthesis and characterization of two, potentially tetradentate, N2S2 Schiff-base ligands, containing a disulfide bond, N,N'-bis(3-phenylprop-2-en-l-ylidene)-2,2'-disulfanediyldianiline (L-1) and N,N'-bis(3,3-diphenylprop-2-en-1-ylidene)- ...
Nickel(II) and copper(II) complexes of two unsymmetrical tetradentate Schiff base ligands [Ni(Me-salabza)] (1), [Cu(Me-salabza)] (2) and [Ni(salabza)] (3), {H(2)salabza = N,N'-bis[(salicylidene)-2-aminobenzylamine] and H2Me-salabza = N,N'-bis[(methylsalicy ...

Two triphenyltin(IV) adducts of difunctional ligands, N-(n-pyridinyl) diphenylphosphinic amide (n = 2 and 4), have been synthesized and characterized by H-1, P-31, Sn-119 NMR and IR spectroscopy. The spectroscopic properties of the complexes were compared ...
The neutral dinuclear complexes [(eta(5)-C5Me5)(2)Rh-2(mu-dhnq)Cl-2] (1) and [(eta(5)-C5Me5)(2)Ir-2(mu-dhnq)Cl-2] (2) (dhnqH(2) = 5,8-dihydroxy-1,4-naphthoquinone) were obtained from the reaction of (eta(5)-C5Me5)M(mu-Cl)Cl (M = Rh, Ir) with dhnqH(2) ...
The development of cyclometalated rhodium and iridium complexes from first-and second-generation naphthaldimine-based poly(propyleneimine) dendrimer scaffolds of the type, DAB-(NH2)(n) (where n = 4 or 8, DAB = diaminobutane) has been accomplished. Four met ...
In recent years quantum antiferromagnets with an intrinsically disordered (“spin liquid”) ground state and an energy gap in the spin excitation spectrum have received a great deal of attention. In search for new experimental realizations of spin-ladder and ...
