6-Amino-3-(prop-2-en-1-yl)-9H-purin-3-ium Tetracopper(I) Hexabromide: Synthesis and X-ray Structure Determination

Abstract

6-Amino-3-(prop-2-en-1-yl)-9H-purin-3-ium tetracopper(I) hexabromide [(C5H5N5(C3H5))2Cu4Br6] (1) is synthesized in this paper. The title compound is characterized by Raman spectroscopy and single crystal X-ray diffraction: monoclinic, Sp.gr. P21/c, Z = 2, unit cell dimensions: a = 8.6870(3), b = 9.7447(2), c = 16.4418(4) Å, β = 100.681(3)°, V = 1367.72(7) Å3 at 150 K. The peculiarities of the metal coordination and distribution of weak interactions are analyzed. The significant role of hydrogen bonds in the construction of 1 crystal structure is shown.
