Abstract

A 3d-4f heterobimetallic material with mixed anions, Ho ₂Cu(TeO₃)₂(SO₄)₂, has been prepared under hydrothermal conditions. Ho₂Cu(TeO ₃)₂(SO₄)₂ exhibits both thermochromism and the Alexandrite effect. Variable temperature single crystal X-ray diffraction and UV-vis-NIR spectroscopy reveal that changes in the Cu ^II coordination geometry result in negative thermal expansion of axial Cu-O bonds that plays a role in the thermochromic transition of Ho ₂Cu(TeO₃)₂(SO₄)₂. Magnetic studies reveal an effective magnetic moment of 14.97 μB. which has a good agreement with the calculated value of 15.09 μB.
