A series of donor-acceptor heteroleptic open sandwiches with formula CpM-M'Pyl (M = B, Al, Ga; M' = Li, Na; Cp = cyclopentadienyl; Pyl = pentadienyl) has been designed in silico using density functional theory. The most stable complexes are those containing boron as a donor atom. A molecular orbital analysis shows that the s character of the lone pair located at the group 13 element is mainly r...

Based on geometrical isomerisation of [Ir(C^N 1 )(C^N 2 )((N^O))]-tris-heteroleptic Ir( iii )-complexes, the augmented transition dipole (TMD) with a preferential horizontal orientation, which is beneficial for their NIR-phosphorescence, reported.

A family of heteroleptic complexes of zinc and magnesium supported by bulky multidentate amino-ether phenolate ligands has been developed; in combination with external chain transfer agents, they constitute efficient binary catalytic systems for the immortal ring-opening polymerisation of cyclic esters.

Vibrational circular dichroism, VCD, gives evidence that the carbon monoxide chromophore in a heteroleptic cyclopentadienyl Ru(ii)-carbonyl complex is very sensitive to the chirality of the metal centre and becomes an excellent probe to define the configuration of chiral metal complexes.

The hierarchical assembly of DSCs containing a new heteroleptic copper(I) complex with a phosphonic acid anchoring ligand is described; it is shown that conventional I(-)/I3(-) electrolytes may be replaced by [Co(bpy)3](2+/3+) with no loss in performance.

Bulky terphenolate ligands allow the synthesis of rare heteroleptic thorium chloride, and borohydride complexes; in the absence of donor solvents, the terphenolate ligands protect the metal ions through neutral Th-η(6)-arene interactions in a thorium bis(arene) sandwich motif.

A novel heteroleptic ruthenium complex carrying a heteroaromatic-4,4'-pi-conjugated 2,2'-bipyridine [Ru(II)LL'(NCS)(2)] (L = 4,4'-bis[(E)-2-(3,4-ethylenedioxythien-2-yl)vinyl]-2,2'-bipyridine, L' = 4,4'-(dicarboxylic acid)-2,2'-bipyridine) was synthesized and used in dye-sensitized solar cells, yielding photovoltaic efficiencies of 9.1% under standard global AM 1.5 sunlight.

Depending on stoichiometry, reactions of the mixed valence Sn(0)/Sn(III) compound Sn(SnAr(3))(2) (1) (Ar = C(6)H(4)(O(i)Pr)(2)-2,6) with the likewise substituted plumbylene PbAr(2) (3) afforded either the homoleptic distannylplumbylene Pb(SnAr(3))(2) (4) or the heteroleptic arylstannylplumbylene Pb(Ar)SnAr(3) (5), a valence isomer of a stannaplumbene.

A one-step method to access to functionalized heteroleptic lanthanide double-decker complexes of phthalocyanine of A7B-type is reported. This optimized statistical method led to two hydroxylated model europium complexes, one of which was further converted into its mesylated and azido derivatives.

Homo- and heteroleptic bis-NHC copper(I) complexes have been efficiently used as carbene transfer reagents to Au and Pd. The simple and straightforward procedure allows for the synthesis of well-known gold complexes as well as novel cationic bis-NHC Pd(II) species.
