摘要

The crystal structures of the two new synthetic compounds Co2TeO3Cl2 and Co2TeO3Br2 are described together with their magnetic properties. Co2TeO3Cl2 crystallize in the monoclinic space group P2(1)/m with unit cell parameters a = 5.0472(6) angstrom, b = 6.6325(9) angstrom, c = 8.3452(10), angstrom, beta = 105.43(1)degrees, Z = 2. Co2TeO3Br2 crystallize in the orthorhombic space group Pccn with unit cell parameters a = 10.5180(7) angstrom, b = 15.8629(9) angstrom, c = 7.7732(5) angstrom, Z = 8. The crystal structures were solved from single crystal data, R = 0.0328 and 0.0412, respectively. Both compounds are layered with only weak interactions in between the layers. The compound Co2TeO3Cl2 has [CoO4Cl2] and [CoO3Cl3] octahedra while Co2TeO3Br2 has [CoO2Br2] tetrahedra and [CoO4Br2] octahedra. The Te(IV) atoms are tetrahedrally [TeO3E] coordinated in both compounds taking the 5s(2) lone electron pair E into account. The magnetic properties of the compounds are characterized predominantly by long-range antiferromagnetic ordering below 30 K. (C) 2005 Elsevier Inc. All rights reserved.
