Beryllium chloride is the chemical compound with the formula BeCl2. Molecular geometry or molecular structure is the three- Dimensional arrangement of the Atoms that constitute a Molecule. In Chemistry, the standard state of a material is its state at 1 bar (100 Kilopascals exactly A chemical compound is a substance consisting of two or more different elements chemically bonded together in a fixed proportion by Mass. A chemical formula is a way of expressing information about the Atoms that constitute a particular Chemical compound, and how the relationship between those atoms changes The solid is a 1-dimensional polymer consisting of edge-shared tetrahedra. [1] In contrast BeF2 is a 3-dimensional polymer, with a structure akin to quartz. Beryllium fluoride is the Chemical compound with the formula BeF2 In the gas phase it is present both as a linear monomer and a bridged dimer with two bridging chlorine atoms where the beryllium atom is 3-coordinate. [2] The linear shape of the monomeric form is as predicted by VSEPR theory, this contrasts with the monomeric forms of some of the dihalides of the heavier members of group 2, e. Valence shell electron pair repulsion (VSEPR theory (1957 is a model in Chemistry, which is used for predicting the shapes of individual Molecules based g. CaF2, SrF2, BaF2, SrCl2, BaCl2, BaBr2, and BaI2 which are all non-linear. Calcium fluoride (CaF2 is an insoluble Ionic compound of Calcium and Fluorine. Strontium fluoride, SrF2, also called strontium difluoride and strontium(II fluoride, is a Fluoride of Strontium. Barium fluoride (BaF2 is a chemical compound of Barium and Fluorine, also known as Barium(II fluoride Strontium chloride (SrCl2 is a Salt of Strontium and Chloride. Barium Chloride is the ionic Chemical compound with the formula BaCl2 Barium bromide is the Chemical compound with the formula BaBr2 Barium iodide occurs in two forms one anhydrous and the other hydrated [2]
BeCl2 can be prepared by treating Be metal with hydrogen chloride:
- Be + 2 HCl → BeCl2 + H2
It hydrolyses upon contact with water to give the aquo complex, [Be(H2O)4]Cl2. [3]
