Chirality at Nitrogen, Phosphorus, and Sulfur

Chirality at Nitrogen, Phosphorus, and Sulfur

Chirality is most prevalent in carbon-based tetrahedral compounds, but this important facet of molecular symmetry extends to sp3-hybridized nitrogen, phosphorus and sulfur centers, including trivalent molecules with lone pairs. Here, the lone pair behaves as a functional group in addition to the other three substituents to form an analogous tetrahedral center that can be chiral.
A consequence of chirality is the need for enantiomeric resolution. While this is theoretically possible for all...

Exceptions to the Octet Rule

Exceptions to the Octet Rule

Many covalent molecules have central atoms that do not have eight electrons in their Lewis structures. These molecules fall into three categories:

Naming Enantiomers

Naming Enantiomers

The naming of enantiomers employs the Cahn–Ingold–Prelog rules that involve assigning priorities to different substituent groups at a chiral center. Each enantiomer, being a distinct molecule, is assigned a unique name by the Cahn–Ingold–Prelog (CIP) rules, also called the R–S system. The prefix R- or S- attached to the chiral centers in an enantiomer is dependent on the spatial arrangement of the four substituents on the chiral center. The R–S system essentially comprises three steps:...

Background:

Nitrido-silicates are an important class of inorganic compounds.
Understanding the synthesis and structure of novel rare-earth nitrido-silicates is crucial for materials discovery.

Purpose of the Study:

To synthesize and characterize a new rare-earth nitrido-silicate, penta-praseodymium trisilicon nona-nitride (Pr5Si3N9).
To elucidate the crystal structure and bonding of this novel compound.

Main Methods:

Single crystal growth via high-temperature reaction in a radio-frequency furnace.
X-ray diffraction analysis to determine the crystal structure.

Main Results:

Single crystals of Pr5Si3N9 were successfully synthesized at 1873 K.
The crystal structure features a 3D network of corner-sharing SiN4 tetrahedra, forming branched chains.
Praseodymium ions (Pr3+) are coordinated by nitrogen atoms, with distances comparable to other rare-earth nitrido-silicates.
