Summary
Researchers synthesized a novel strontium imidonitridophosphate, SrP3N5NH, under high pressure and temperature. This discovery reveals an unprecedented network structure stabilized by hydrogen bonds, expanding knowledge of nitridophosphate materials.
Area of Science:
- Solid-state chemistry
- Materials science
- Crystallography
Background:
- Nitridophosphates and imidonitridophosphates exhibit diverse structures.
- Novel compounds with unique structural motifs are of significant scientific interest.
Purpose of the Study:
- To synthesize and characterize a highly condensed strontium imidonitridophosphate.
- To explore new structural types within the imidonitridophosphate family.
Main Methods:
- High-pressure (8 GPa) and high-temperature (1100 °C) synthesis.
- Utilized Sr(N3)2, P3N5, and NH4Cl as precursors.
- Single-crystal growth facilitated by in situ SrCl2 formation acting as a mineralizer.
Main Results:
- Successfully synthesized SrP3N5NH, a novel highly condensed strontium imidonitridophosphate.
- Determined the crystal structure (P21/c) revealing an unprecedented three-nodal P/N(H) network.
- Observed structure-directing effect of hydrogen bonds, a novel phenomenon for imidonitridophosphates.
Conclusions:
- The synthesis of SrP3N5NH expands the known structural diversity of nitridophosphates.
- The identified network structure and hydrogen bonding influence offer new insights into material design.

Hydrogen bonds are weak attractions between atoms that have formed other chemical bonds. One of these atoms is electronegative, like oxygen, and has a partial negative charge. The other is a hydrogen atom that has bonded with another electronegative atom and has a partial positive charge.
Hydrogen Bonds Control the World!
Because hydrogen has very weak electronegativity when it binds with a strongly electronegative atom, such as oxygen or nitrogen, electrons in the bond are unequally shared....

A hydrogen bond is formed when a weakly positive hydrogen atom already bonded to one electronegative atom (for example, the oxygen in the water molecule) is attracted to another electronegative atom from another polar molecule, such as water (H2O), hydrogen fluoride (HF), or ammonia (NH3). The huge electronegativity difference between the H atom (2.1) and the atom to which it is bonded (4.0 for an F atom, 3.5 for an O atom, or 3.0 for an N atom), combined with the very small size of an H atom...

Compared to ionic bonds, which results from the transfer of electrons between metallic and nonmetallic atoms, covalent bonds result from the mutual attraction of atoms for a “shared” pair of electrons.

Chemical bonding theories were pioneered by American chemist Gilbert N. Lewis. He developed a model called the Lewis model to explain the type and formation of different bonds. Chemical bonding is central to chemistry; it explains how atoms or ions bond together to form molecules. It explains why some bonds are strong and others are weak, or why one carbon bonds with two oxygens and not three; why water is H2O and not H4O.

01:23IR Spectrum Peak Broadening: Hydrogen Bonding
1.8K
The vibrational frequency of a bond is directly proportional to its bond strength. As a result, stronger bonds vibrate at higher frequencies, while weaker bonds vibrate at lower frequencies. The stretching vibration of the strong O–H bond in alcohols and phenols (very dilute solution or gas phase) appears as a sharp peak at 3600–3650 cm−1.
However, the extent of hydrogen bonding influences the observed stretching frequency and band broadening. Intermolecular or intramolecular...
