Abstract
A new metal orthoborate compound, cobalt dinickel orthoborate, CoNi 2 (BO 3 ) 2 has been successfully synthesized for the first time. The title compound was synthesized by thermally-induced solid-state chemical reaction at 900°C between the initial reagents of Co(NO 3 ) 2 · 6H 2 O, Ni(NO 3 ) 2 · 6H 2 O and H 3 BO 3 which were mixed with the mol ratio of 1: 2: 2 respectively. The obtained product was structurally characterized by X-ray powder diffraction technique. It has been found that the CoNi 2 (BO 3 ) 2 crystallizes in the kotoite type and isostructural with the compounds having the chemical formula M 3 (BO 3 ) 2 where M—Mg, Co and Ni. The synthesized compound belongs to the orthorhombic crystal system with the refined unit cell parameters of a = 5.419(9) Å, b = 8.352(0) Å, c = 4.478(8) Å and Z = 2. The space group was determined as Pnmn . Further characterizations by FTIR, elemental analysis and thermal analysis were also performed.
