Summary
The crystal structure of strontium sodium thiophosphate octahydrate, SrNa(2)(P(2)S(6))·8H(2)O, reveals layered arrangements of cations and anions. Hydrogen bonding stabilizes these layers, similar to its calcium analogue.
Area of Science:
- Inorganic Chemistry
- Crystallography
- Materials Science
Background:
- Strontium and sodium thiophosphates are compounds with interesting structural and chemical properties.
- Understanding the crystal structure of novel compounds is crucial for predicting their behavior and potential applications.
Purpose of the Study:
- To determine and describe the crystal structure of SrNa(2)(P(2)S(6))·8H(2)O.
- To compare its structure with that of its calcium analogue.
Main Methods:
- Single-crystal X-ray diffraction was used to elucidate the crystal structure.
- Analysis of bond lengths, coordination polyhedra, and intermolecular interactions was performed.
Main Results:
- SrNa(2)(P(2)S(6))·8H(2)O is isotypic with its calcium analogue.
- The crystal structure features layered arrangements of Sr(2+), Na(+), and (P(2)S(6))(4-) anions.
- The structure is stabilized by O-H⋯S hydrogen bonds between adjacent layers.
Conclusions:
- The crystal structure of SrNa(2)(P(2)S(6))·8H(2)O is characterized by a layered architecture.
- The observed structural features, including hydrogen bonding, are consistent with its isotypic relationship to the calcium analogue.

02:42Ionic Crystal Structures
Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

02:48Ionic Bonding and Electron Transfer
Ions are atoms or molecules bearing an electrical charge. A cation (a positive ion) forms when a neutral atom loses one or more electrons from its valence shell, and an anion (a negative ion) forms when a neutral atom gains one or more electrons in its valence shell. Compounds composed of ions are called ionic compounds (or salts), and their constituent ions are held together by ionic bonds: electrostatic forces of attraction between oppositely charged cations and anions.
03:34Ionic Compounds: Formulas and Nomenclature
An element composed of atoms that readily lose electrons (a metal) can react with an element composed of atoms that readily gain electrons (a nonmetal) to produce ions through complete electron transfer. The compound formed by this transfer is stabilized by the electrostatic attractions (ionic bonds) between the oppositely charged ions.

Tetrahedral Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...

03:46Qualitative Analysis
For solutions containing mixtures of different cations, the identity of each cation can be determined by qualitative analysis. This technique involves a series of selective precipitations with different chemical reagents, each reaction producing a characteristic precipitate for a specific group of cations. Metal ions within a group are further separated by varying the pH, heating the mixture to redissolve a precipitate, or adding other reagents to form complex ions.
