Three discrete supramolecular self-assembled arsenic(iii) complexes including an unusual S(4)-symmetric tetranuclear [As(4)L(2)Cl(4)] metallacyclophane and two diastereomeric cis/trans-[As(2)LCl(2)] metallacycle intermediates co-crystallize within a single crystal lattice.

A sixfold interpenetrated microporous MOF has been constructed from a heterometallic tetranuclear cluster. The framework contains two types of 1D micro-channels along different directions. Moreover, this compound exhibits high selective gas sorption for H(2) over N(2).

By variation of the zinc bonded alkyl group significantly different post-oxygenation products, the novel zinc alkylperoxide and the tetranuclear zinc oxo-encapsulated cluster, were derived from the controlled oxygenation of the corresponding alkylzinc complexes with a pyrrolylketiminate ligand.

Three dinuclear [Ln2H2OL(1)2(acac)2]·solvent (1, Ln = Gd, solvent = 2CH2Cl2; 2, Ln = Tb, no solvent; 3, Ln = Er, solvent = (C2H5)2O), and two tetranuclear lanthanide clusters [Ln4(μ3-OH)2L(2)2(acac)6]·2(solvent) (4, Ln = Tb, solvent = CH3OH; 5, Ln = Dy, solvent = CH3CN) were characterized in terms of structure, fluorescence and magnetism. The dinuclear lanthanide complexes were constructed by a...

Palladium (Pd) generally prefers low oxidation states. So far, no stable Pd compound with a +5 oxidation state is known. Here, we report two multinuclear Pd compounds containing Pd centers ligated by five silicon (Si) atoms. A thermal condensation reaction of [{1,2-C(6)H(4)(SiMe(2))(SiH(2))}Pd(II)(Me(2)PCH(2)CH(2)PMe(2))] (Me = methyl) afforded two stereoisomers of dinuclear Pd(II) compounds an...

The reaction of 1,3-bis(4,6-dimethylpyridyl-2-imino)isoindoline and palladium acetate in methanol selectively yields the expected acetato palladium N,N,N-chelate or a cyclometalated tetranuclear dimer depending on the stoichiometry of the reactants.

Three structurally and magnetically different tetranuclear Ni(II) complexes have been isolated and magnetically characterized, emphasizing the effect of the reaction solvent and organic ligand substitution on the chemical identity of cluster compounds.

Four tetranuclear 3d-4f complexes with the 4f centers bridged solely by end-on azide bridges were reported. The [CuTb]2 compound displays single-molecule-magnet behavior with hysteresis loops observed at up to 2.4 K.

Two diastereoisomers of tetranuclear cyclometallated iridium complexes, either having an inner core of HEXOL-type [Ir(IrCl2)3]6+ unit and a surface of six chiral, didentate, cyclometallated ligands, are stereoselectively synthesized from an enantiopure pinenopyridine derivative.

The chiral ligand S-1,2-bis(1H-benzimidazol-2-yl)ethanol, 1, reacts with manganese(II) salts to form cubanes which readily undergo oxidation reactions leading either to a tetranuclear manganese(II,III) mixed valence complex 4 or to a tetranuclear complex of ligand 5 where the secondary alcohol has been oxidised to an enolate. N-methylation of ligand 1 slows the oxidation reaction and stable man...
