“…Crystals of [(iPr 2 -bimy) 6 Cu 10 S 8 Hg 3 ] 6 have ab road emission at about 800 nm;t his can be contrasted with the recent reports by Eichhçfer and co-workers on the luminescentp roperties of similarly sized [Cu 12 S 6 (L\ L)] clusters (L\ L = bidentate phosphine ligand), with strong, sharpe missions being observed at about 700 nm.

As a part of efforts to prepare new "metallachalcogenolate" precursors and develop their chemistry for the formation of ternary mixed-metal chalcogenide nanoclusters, two sets of thermally stable, N-heterocyclic carbene metal-chalcogenolate complexes of the general formula [(IPr)Ag-ESiMe3] (IPr=1,3-bis(2,6-diisopropylphenyl)imidazolin-2-ylidene; E=S, 1; Se, 2) and [(iPr2-bimy)Cu-ESiMe3]2 (iPr2-bimy=1,3-diisopropylbenzimidazolin-2-ylidene; E=S, 4; Se, 5) are reported. These are prepared from the reaction between the corresponding carbene metal acetate, [(IPr)AgOAc] and [(iPr-bimy)CuOAc] respectively, and E(SiMe3 )2 at low temperature. The reaction of [(IPr)Ag-ESiMe3] 1 with mercury(II) acetate affords the heterometallic complex [{(IPr)AgS}2Hg] 3 containing two (IPr)Ag-S(-) fragments bonded to a central Hg(II), representing a mixed mercury-silver sulfide complex. The reaction of [(iPr2-bimy)Cu-SSiMe3]2, which contains a smaller N-heterocyclic-carbene, with mercuric(II) acetate affords the high nuclearity cluster, [(iPr2-bimy)6Cu10S8Hg3]6. The new N-heterocyclic carbene metal-chalcogenolate complexes 1, 2, 4, 5 and the ternary mixed-metal chalcogenolate complex 3 and cluster 6 have been characterized by multinuclear NMR spectroscopy ((1)H and (13)C), elemental analysis and single-crystal X-ray diffraction.

[Hg₄Te₈(Te₂)₄]⁸⁻: A Heavy Metal Porphyrinoid Embedded in a Lamellar Structure

The use of ionic liquids (C C Im)[BF ] with long alkyl chains (n=10, 12) in the ionothermal treatment of Na [HgTe ] led to lamellar crystal structures with molecular macrocyclic anions [Hg Te ] (1), the heaviest known topological relative of porphyrin. [Hg Te ] differs from porphyrin by the absence of an electronic π-system, which prevents a "global" aromaticity. Quantum chemical studies reveal instead small ring currents in the pyrrole-type five-membered rings that indicate weak local (σ) aromaticity. As a result of their lamellar nature, the compounds are promising candidates for the formation of sheets containing chalcogenidometalate anions.

From Cluster to Polymer: Ligand Cone Angle Controlled Syntheses and Structures of Copper(I) Alkynyl Complexes

et al. 2016

Copper(I) alkynyl complexes have attracted tremendous attention in structural studies,a sl uminescent materials, and in catalysis,and homoleptic complexes have been reported to form polymers or large clusters.H erein, six unprecedented structures of Cu I alkynyl complexes and ap rocedure to measure the cone angles of alkynyll igands based on the crystal structures of these complexes are reported. An increase of the alkynyl cone angle in the complexes leads to am odulation of the structures from polymeric [((PhCCCC)Cu) 2 -(NH 3 )] 1 ,t oal arge cluster [(TripCCCC)Cu] 20 (MeCN) 4 ,t o ar elatively small cluster [(TripCC)Cu] 8 (Trip = 2,4,6-iPr 3 -C 6 H 2 ). The complexes exhibit yellow-to-red phosphorescence at ambient temperature in the solid state and the luminescence behavior of the Cu 20 cluster is sensitive to acetonitrile.
