Abstract
The monoclinic modification of complex [Cu(NH3)4](ReO4)2 salt is studied by single crystal X-ray diffraction in the range of 100-410 K. Crystallographic data at 300 K are as follows: a = 10.6123(3) Å, b = 7.5443(2) Å, c = 15.2261(4) Å, b = 108.406(1)°, V = 1156,67(5) Å3, space group Р 21/ n , Z = 4, d x = 3.623 g/cm3. The coordination environment of the Cu atom is a distorted square formed by four nitrogen atoms; Cu-N of 1.997-2.018 Å; supplemented with contacts with two oxygen atoms Cu…О 2.472 Å and 2.598 Å. A comparative crystallochemical analysis with the triclinic modification of [Cu(NH3)4](ReO4)2 known in the literature is performed.
