Structural Inorganic Chemistry – Solid State Chemistry

Flashcards covering key terms and concepts from the course on Structural Inorganic Chemistry.

Solid State Chemistry

The study of the synthesis, structure, and properties of solid phase materials.

Unit Cell

The smallest repeating unit in a crystal lattice that defines its structure.

Crystalline Solid

A solid in which the constituent atoms are arranged in an orderly repeating pattern over large distances.

Amorphous Solid

A solid with disordered structure and no long-range order.

Coordination Number

The number of nearest neighbor atoms surrounding a central atom in a crystal.

Atomic Packing Factor (APF)

The fraction of volume in a crystal structure that is occupied by atoms.

Cubic Close Packed Structure (ccp)

A crystal structure where atoms are packed tightly together, forming an arrangement that repeats every three layers.

Hexagonal Close Packed Structure (hcp)

A crystal structure characterized by an arrangement of atoms that forms a hexagonal pattern.

Lattice Parameters

The parameters (edge lengths and angles) that define the geometry of a unit cell.

8-N Concept

A concept in solid state chemistry relating to the coordination of atoms in a crystal.

Dislocation

A defect in the crystal structure that can affect its mechanical properties.

Metal-organic Frameworks (MOFs)

Hybrid structures composed of metal ions or clusters coordinated to organic ligands.

Sorption

The process of adsorption or absorption of molecules onto a surface.

Point Defects

Imperfections in a crystal structure occurring at a single lattice site.

High-Temperature Synthesis

A method of material synthesis that occurs at elevated temperatures, often resulting in specific structural properties.

Hard Sphere Model

A model in solid state chemistry where atoms are treated as hard spheres that touch each other.

Crystal System

A classification system for crystal structures based on their unit cell geometry.

Face-Centered Cubic (FCC)

A cubic crystal structure where atoms are located at each corner and the center of each face of the cube.

Body Centered Cubic (BCC)

A crystal structure where atoms are located at each corner of the cube and a single atom is in the center.

Lattice Types

Different arrangements of points in space that define a crystal structure.

Magnetism

A property of materials that describes their ability to be influenced by magnetic fields.

Defects in Solids

Irregularities in the atomic structure of a solid that affect its properties.
