A Systematic Investigation of Coinage Metal Carbonyl Complexes Stabilized by Fluorinated Alkoxy Aluminates

“…The distances and angles within the anion are in good agreement with the literature. [82,83] A 4 ] À (7): Compound 7 crystallizes in the monoclinic space group P2/n. The cation has a C 2v symmetry that is induced by a C 2 axis, which runs vertically through the Cl1 atom and the midpoint between the two Au + centers.…”

Linear π-conjugated units of theD∞hpoint group as superior ultraviolet birefringent units

“…In addition, we found several linear groups similar to (BO 2 ) − that also belong to the D ∞h point group, they are (CN 2 ) 2− , (NO 2 ) + and (BN 2 ) 3− . 19 The basic functions of irreducible representations from atomic orbitals in (CN 2 ) 2− , (NO 2 ) + and (BN 2 ) 3− are also identical in symmetry with (BO 2 ) − . Therefore, it is conclusive that the properties of these linear groups in terms of electronic structure are similar to (BO 2 ) − , and their microscopic properties related to birefringence will be equally excellent.…”
