Abstract

The hydrothermal reactions of CuBr₂, CuBr, and ethylenediamine have resulted in the synthesis of two new compounds. [Cu(H₂NCH₂CH₂NH₂)₂] [{Cu₂Br₄}] has a two-dimensional sheet structure while [Cu(H₂NCH₂CH₂NH₂)₂] [{Cu₅Br₇}] crystallizes as a three-dimensional network. Both compounds were characterized by single-crystal X-ray diffraction. The following are the crystal data for [Cu(H₂NCH₂CH₂NH₂)₂] [{Cu₂Br₄}] (1), triclinic space group P1 (No. 1) with a=6.491(1) Å, b=8.012(2) Å, c=8.070(2) Å, α=107.713(5)°, β=109.976(4)°, γ=96.815(4)°, Z=1, d_calc=2.88 gcm^-3, and wR2 (R1)=0.093(0.037), and [Cu(H₂NCH₂CH₂NH₂)₂] [{Cu₅Br₇}] (2), orthorhombic space group Pnma (NO. 62), with a=12.886(4) Å, b=16.776(5) Å, c=9.170(3) Å, Z=4, d_calc=3.55 gcm^-3, and wR2 (R1)=0.099 (0.073). Both structures consist of anionic one-dimensional copper(I) bromide chains interspersed with cationic [Cu(H₂NCH₂CH₂NH₂)₂] ²⁺ units.
