Abstract
[RhPy4Cl2]Cl·4H2O (I), [RhPy4Cl2]ReO4 (II), [RhPy4Cl2]ClO4 (III), and [RhPy4Cl2]ReO4·2H2O complex salts were synthesized. The crystal structure of compounds II (P4/ncc, a = 25.5655(3) Å, c = 14.3521(4) Å), III (P21/n, a = 13.5308(3) Å, b = 15.1044(5) Å, c = 23.3457(8) Å, β = 93.327°), and dyhydrate of II (Pbcm, a = 10.6199(9) Å, b = 10.4964(9) Å, c = 22.9834(16)Å) was determined by X-ray diffraction analysis. The thermal transformations of the complexes were studied by differential thermal analysis. The substances were characterized by IR spectroscopy, XRPA, and element analysis
