Abstract:
A new microporous polyborate, NaCuB 7 O 12 . n H 2 O, is synthesized using boric acid as a flux. It contains a 14-membered ring framework built up by CuO 6 octahedra, BO 4 tetrahedra and BO 3 triangles. The spin-1/2 dimers of Cu 2+ ions are connected by BO 3 to form an infinite ladder along the b -axis. Magnetic susceptibility data between 2 and 330 K are presented, and the data are accurately fitted by theoretical predictions of Bleaney-Bowers for the spin-1/2 dimer, with J/k B = -153.8 K, and g = 1.98, where J is the intradimer exchange interaction constant and g is the Landé g factor.
