Radicals: Electronic Structure and Geometry

5.3K
This lesson delves into the geometry of a radical, which is influenced by the electronic structure of the molecule. The principle is similar to that of a lone pair, where the unpaired electron influences the geometry at the radical center.
Accordingly, the structure of a trivalent radical lies between the geometries of carbocations and carbanions. An sp2-hybridized carbocation is trigonal planar, while an sp3-hybridized carbanion is trigonal pyramidal. Here, the difference in geometry is...

The Seven Crystal Systems: Overview

19
Crystals with various point group symmetries belong to different crystal classes, which are synonymous terms. Despite being in the same class, crystals may have distinct shapes, like cubes and octahedra. There are 32 three-dimensional point groups, all of which are systematically divided into seven crystal systems.The basic cubic crystal system, exemplified by NaCl, features orthogonal vectors (α = β = �� = 90°) of equal lengths (a = b = c). When specific...

Crystallographic Point Groups

15
Crystallographic point groups represent the various symmetry operations that can occur within crystals. They are unique in that at least one point will always remain unchanged during these actions. For instance, consider the triclinic system. This system, devoid of any axis or plane of symmetry, aligns with the C1 and Ci point groups.where Cᵢ is characterized solely by a center of inversion.Contrastingly, the monoclinic system introduces an element of symmetry. This system with one plane...

Newman Projections

Different notations are used to represent the three-dimensional structure of molecules on two-dimensional surfaces. One of the most commonly used representations is the dash-wedge formula. The dashed wedges, solid wedges, and the plane lines indicate the groups situated behind the plane, coming out of the plane, and in the plane, respectively.
The organic molecules rotate across the single bonds leading to numerous temporary three-dimensional structures of varying energy known as...

Area of Science:

  • Coordination chemistry
  • Supramolecular chemistry
  • Materials science

Background:

  • Metallo-supramolecular chemistry enables the construction of complex architectures.

  • Utilized five distinct chemical components for assembly.
  • Employed three different types of dynamic coordination interactions.
  • Characterized the resulting metallo-supramolecular structure.

Main Results:

  • Successfully constructed a metallo-supramolecular trigonal prism (P).
  • The prism assembly relies on the interplay of three unlike dynamic coordination motifs.
  • Key motifs include a zinc(II)-phenanthroline-terpyridine complex ([Zn(1)(4)]2+, HETTAP), a copper(I)-phenanthroline-pyridine complex ([Cu(2)(5A)]+, HETPYP-I), and a pyridine → zinc(II)-porphyrin interaction.

Conclusions:
