Charge assisted hydrogen bond
WebFeb 12, 2024 · The Pd−C(2) bond length was found to be within the normal range (2.134 Å) and the C(2)−H and Pd−H distances were 1.090 and 2.573 Å, respectively. This suggests that the C(2)−H bond is not polarized and the metal-to-Hydride interaction is weak, indicating the absence of agostic character in this intermediate state. WebFeb 17, 2024 · This study presents a new charge-assisted hydrogen bonding (H-bonding) motif, by exploiting inorganic ammonium (NH 4 +) cations as H-bond donors, to regulate the assembly of C 2-symmetric carboxylic tectons for building robust H-bonded frameworks with permanent ultra-micropores and open oxygen sites.
