Abstract:
A series of 25 × 25 × 25 Å(3) octahedral coordination cages [Pd6(L)8](NO3)12 (L = L(1), 1; L = L(2), 2; L(1) = tris(6-quinolyl)trimesic ester; L(2) = N,N',N''-tris(6-quinolyl)-1,3,5-benzenetricarboxamide) is reported. L(1) and L(2) are indistinguishable for construction of octahedral nanocages, and thus the desirable mixed ligand nanocage comprising a statistical ligand distribution ([Pd6(L(1))n(L(2))8-n](NO3)12, 3) can be efficiently constructed. However, the nanocages are distinguishable for functions such as photoluminescence (PL) and catalysis. The PL intensity is in the order 1≫3 > 2, wherein 1 shows a blue emission. The nanocages show excellent catalytic activity for the C-C coupling reaction under mild conditions in the order 1 > 3 > 2, presumably owing to the spacer-functional groups.

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the...
