Abstract
Synthesis, structure, and magnetic properties of copper bromide CuL2Br2 with 3-amino-4-ethoxycarbonylpyrazole (L) are presented. The CuL2Br2 is a 1D polymer complex and crystal structure has triclinic symmetry with space group P-1. The examined compound has thermochromic properties (russet ↔ light red), and its magnetic properties are changed from paramagnetic to nonresonance and ferromagnetic ones after heat treatment (300 → 77 → 300 K) or pressure treatment (1 → 3,000 → 1 atm).
