Monomeric selenopalladates and selenoplatinates

Sequential bottom-up and top-down processing for the synthesis of transition metal dichalcogenide nanosheets: the case of rhenium disulfide (ReS2)

“…ReS 2 thin films were produced by AACVD on glass substrates at 550 1C using the single source precursor [Re(S 2 CC 6 H 5 )(S 3 CC 6 H 5 ) 2 ]. 36 Characterization of the films by Raman spectroscopy agreed with the previously reported spectra for ReS 2 5,28 and powder X-ray diffraction (pXRD) measurements showed a preferred orientation in the (010) plane whilst scanning electron microscopy (SEM) revealed the lamellar morphology of the individual crystallites within the thin film. EDX spectrum mapping of the Re L a (8.6 keV) and S K a (2.3 keV) lines demonstrated the homogeneous co-localisation of both elements in the thin film.…”

Stepwise Construction of Oligomeric 1,2‐Diselenolene Platinum(IV) Complexes

“…Herein we describe the results obtained following this approach that, in contrast to the well-known squareplanar dichalcogenene species, leads to an unprecedented series of tris-, penta-, and hepta-1,2-diselenolene oligomeric complexes of which the mononuclear chiral {Pt IV Se 6 [10] shows the metal center in an octahedral coordination environment (see Figure 1 a), [11] with typical Pt IV -Se separations of around 2.46 . [12] Complex 1 crystallizes in the orthorhombic chiral P2 1 2 1 2 1 space group owing to a spontaneous resolution phenomena leading to a conglomerate of crystalline enantiomers. [13] The three-blade propeller-like structure of 1 in the crystal studied is the anticlockwise L enantiomer.…”

“…Only one similar mononuclear {Pt IV Se 6 } octahedral structure has been (Se 4 ) 2À bidentate ligands. [12] In regard to compound 2, only a dimeric [Pt IV 2 Se 4 C 2 Cl 2 ] compound is known, [22] with a {Pt IV 2 Se 2 } core have two short and two long equivalent Pt À Se bonds of 2.42 and 2.62 , in sharp contrast to the inequivalently distorted rhombic {Pt IV 2 Se 2 } core found in 2.…”

“…Single-crystal X-ray diffraction [10] shows the metal center in an octahedral coordination environment (see Figure 1 a), [11] with typical Pt IV -Se separations of around 2.46 . [12] Complex 1 crystallizes in the orthorhombic chiral P2 1 2 1 2 1 space group owing to a spontaneous resolution phenomena leading to a conglomerate of crystalline enantiomers.

“…Complex [Pt IV (pds) 3 ]Na 2 ⋅6 H 2 O ( 1 ) was synthesized by the reaction of pds 2− ligand with Pt II Cl 2 (in a 3:1 molar ratio). Single‐crystal X‐ray diffraction10 shows the metal center in an octahedral coordination environment (see Figure 1 a),11 with typical Pt IV ‐Se separations of around 2.46 Å 12. Complex 1 crystallizes in the orthorhombic chiral P 2 1 2 1 2 1 space group owing to a spontaneous resolution phenomena leading to a conglomerate of crystalline enantiomers 13.…”
