Syntheses, structures and properties of three nonmetal borates with salicylic acid and organic amines
摘要:
Three new borates containing nonmetal compounds, [C4H12N][BO4(C(7)H4(O))(2)] (1), [C8H20N][BO4(C7H4O)2] (2) and [C6H18N2](0.5)[BO4(C7H4O)(2)] (3) have been prepared, aiming at the formation of extended supramolecular networks with organic-inorganic hybrid materials of salicylic acid and boric acid. The corresponding compounds have been characterized by chemical and spectroscopic techniques. X-ray diffraction analyses of available single crystals revealed that the molecular structures of the three compounds have the same isolated [BO4(C7H4O)(2)] anion. The [BO4(C7H4O)(2)] anion with a distorted BO4 tetrahedron is formed by bidentate coordination of the B atom to two salicylic acid molecules via the O atoms of the central carboxyl and alpha-hydroxyl groups. The three compounds display violet luminescence with emission maxima around 365 nm. (C) 2010 Elsevier B.V. All rights reserved.
