Abstract
The reaction of Pd(OAc)2 with free carbodicarbene (CDC) generates a Pd acetate trinuclear complex 1 via intramolecular C(sp3 )-H bond activation at one of the CDC methyl side arms. The solid structure of 1 reveals the capability of CDC to facilitate a double dative bond with two palladium centers in geminal fashion. This is attributed to the chelating mode of CDC, which can frustrate π-conjugation within the CDC framework. Such effect maybe also amplified by ligand-ligand interaction. The formation of other gem-bimetallic Pd-Pd, Pd-Au, and Ni-Au provides further structural evidence for this proof-of-concept in selective installation. Structural analysis is supported by computational calculations based on state-of-the-art energy decomposition analysis (EDA) in conjunction with natural orbitals for chemical valence (NOCV) method.

Abstract
Rhodium dinuclear complexes (1-3) with azulene moieties as equatorial ligands were obtained by reacting Rh2 (OAc)4 with guaiazulene-2-carboxylic acid, azulene-2-carboxylic acid, and azulene-1-carboxylic acid, respectively. The molecular structures in their crystalline states were determined by X-ray diffraction to be 1 ⋅ (H2 O)2 , 1 ⋅ (MeCN)2 , 2 ⋅ (MeCN)2 , and 3 ⋅ (DMF)2 , which were coordinated with the crystallization solvent at the axial positions. Among these, the crystal packing of 1 ⋅ (H2 O)2 , 1 ⋅ (MeCN)2 , and 3 ⋅ (DMF)2 revealed the formation of one-dimensional stacked chains nearly along the axial direction and of two-dimensional stacked sheets along the equatorial direction. In addition, it was found that 1 ⋅ (H2 O)2 contained cavities that could adsorb CO2 , thereby inducing structural changes. Furthermore, redox measurements revealed the stepwise one-electron redox behaviors of these complexes, indicating the intramolecular interactions between the azulene units. In addition, transient absorption measurements suggested the presence of an ultrafast intersystem crossing caused by the heavy-atom effect of rhodium, and an extended lifetime of the triplet state due to the energy migration among the azulene ligands.

Abstract
Acetetracenylene-1,2-dione reacted with 3-ethylrhodanine in the presence of piperidine and Hantzsch ester via a Knoevenagel condensation-reduction sequence to give a tetracene-rhodanine adduct. This reduced Knoevenagel product exhibited magenta luminescence with a fluorescence quantum yield of φ = 0.34 and fluorescence lifetime of τ = 13.2 ns in toluene. Electrochemical studies and charge carrier transport measurements revealed ambipolar properties with hole and electron mobilities of 5.1 × 10-7 and 1.6 × 10-4 cm2/(V s), respectively.
