Web3 apr. 2024 · Each CuII atom has a distorted trigonal–bipyramidal environment formed by the three nitrogen atoms of the deprotonated bridging 3-(2-pyridyl)-5-ethyl-triazolate unit, oxygen atoms of the OAc− group and dmf molecule. In the crystal, C—H⋯O hydrogen bonds link the molecules into chains running along the c-axis direction. WebIf the molecule is made up of only σ-bonds (sigma bonds), it is a single bond; the C-C and C-H bonds are single bonds and are connected by only one hand. In the case of a single bond, the σ-bond can be rotated. For example, in ethane, they are all single bonds and they are all σ-bonds.

http://ursula.chem.yale.edu/~chem220/chem220js/STUDYAIDS/thermo/atomization.html WebHydrogen bonds (H-bonds) are a specific type of electrostatic interaction between a proton attached to an electronegative atom (such as N or O) and a lone pair of electrons on an electronegative atom such as N, O, or F. The former is called the H-bond donor, the latter the H-bond acceptor.
