Abstract

Molecular structural design is a compelling strategy to develop new compounds and optimize the crystal structure by atomic-scale manipulation. Herein, two fluorine-beryllium borates, BaMgBe2(BO3)2F2 and BaCaBe2(BO3)2F2, have been rationally designed to overcome the structural instability problems of Sr2Be2B2O7 (SBBO). When relatively large Ba atoms were introduced, the [Be6B6O15]? double layers of SBBO were successfully broken, generating flexible [Be3B3O6F3]? single layers. Also, the strategy adopted in this work has many implications in understanding the structural chemistry and designing novel optical functional materials in a beryllium borate system.

Beryllium

See more Beryllium products. Beryllium (atomic symbol: Be, atomic number: 4) is a Block S, Group 2, Period 2 element with an atomic weight of 9.012182. Beryllium Bohr ModelThe number of electrons in each of Beryllium's shells is [2, 2] and its electron configuration is [He] 2s2. The beryllium atom has a radius of 112 pm and a Van der Waals radius of 153 pm. Beryllium is a relatively rare element in the earth's crust; it can be found in minerals such as bertrandite, chrysoberyl, phenakite, and beryl, its most common source for commercial production. Beryllium was discovered by Louis Nicolas Vauquelin in 1797 and first isolated by Friedrich Wöhler and Antoine Bussy in 1828. Elemental BerylliumIn its elemental form, beryllium has a gray metallic appearance. It is a soft metal that is both strong and brittle; its low density and high thermal conductivity make it useful for aerospace and military applications. It is also frequently used in X-ray equipment and particle physics. The origin of the name Beryllium comes from the Greek word "beryllos," meaning beryl.

Boron

See more Boron products. Boron Bohr ModelBoron (atomic symbol: B, atomic number: 5) is a Block P, Group 13, Period 2 element with an atomic weight of 10.81. The number of electrons in each of boron's shells is 2, 3 and its electron configuration is [He] 2s2 2p1. The boron atom has a radius of 90 pm and a Van der Waals radius of 192 pm. Boron was discovered by Joseph Louis Gay-Lussac and Louis Jacques Thénard in 1808 and was first isolated by Humphry Davy later that year. Boron is classified as a metalloid is not found naturally on earth. Elemental BoronAlong with carbon and nitrogen, boron is one of the few elements in the periodic table known to form stable compounds featuring triple bonds. Boron has an energy band gap of 1.50 to 1.56 eV, which is higher than that of either silicon or germanium. The name Boron originates from a combination of carbon and the Arabic word buraqu meaning borax.

Fluorine

Fluorine is a Block P, Group 17, Period 2 element. Its electron configuration is [He]2s22p5. The fluorine atom has a covalent radius of 64 pm and its Van der Waals radius is 135 pm. In its elemental form, CAS 7782-41-4, fluorine gas has a pale yellow appearance. Fluorine was discovered by André-Marie Ampère in 1810. It was first isolated by Henri Moissan in 1886.
