Abstract

More than 50 yr. after the proposal of the Dewar-Chatt-Duncanson model for the binding of olefins to transition-metal atoms, the first structurally characterized example of a silver-C2H4 complex [Ag(h2-C2H4)3]+ was obtained with the help of the very weakly coordinating [Al{OC(CF3)3}3]- ion. By contrast, earlier gas-phase investigations only suggested the existence of [Ag(h2-C2H4)x]+ ions (x = 1 and 2). The crystal structure of the title compd. is given and it was compared with DFT calcd. structure. [on SciFinder (R)]

Crystal structure

In crystallography, crystal structure is a description of the ordered arrangement of atoms, ions, or molecules in a crystalline material. Ordered structures occur from the intrinsic nature of the constituent particles to form symmetric patterns that repeat along the principal directions of three-dimensional space in matter. The smallest group of particles in the material that constitutes this repeating pattern is the unit cell of the structure.

Cubic crystal system

In crystallography, the cubic (or isometric) crystal system is a crystal system where the unit cell is in the shape of a cube. This is one of the most common and simplest shapes found in crystals and minerals. There are three main varieties of these crystals: Primitive cubic (abbreviated cP and alternatively called simple cubic) Body-centered cubic (abbreviated cI or bcc) Face-centered cubic (abbreviated cF or fcc) Note: the term fcc is often used in synonym for the cubic close-packed or ccp structure occurring in metals.

Silver

Silver is a chemical element with the symbol Ag (, derived from the Proto-Indo-European h2erǵ 'shiny, white') and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.
