Hidden Complexity of a Simple Compound: Unexpected Polymorphism of Tetranuclear Platinum (II) Acetate Pt4(OCOMe)8
Polymorphism is an infrequent phenomenon in platinum group complexes. Surprisingly, we found a new monoclinic crystal modification (C2/c) of a relatively simple compound, platinum (II) acetate Pt4(OCOMe)8 (2) (monoclinic C2/c (2), monoclinic P21/c (3) and tetragonal P43212 (4)). The polymorph was prepared by a novel synthetic protocol and structurally identified by single-crystal X-ray diffraction (SC-XRD) using synchrotron radiation X-ray source. Examination of the intermolecular interaction by Hirshfeld surface analysis of 2 and its comparison with another known polymorphs - monoclinic (P21/c, 3) and tetragonal (P43212, 4) ones, - as well as analysis of packaging motifs revealed the responsibility of weak interactions for their formation.
期刊介绍：
Journal is an interdisciplinary publication covering all aspects of structural chemistry, including the theory of molecular structure and chemical bond; the use of physical methods to study the electronic and spatial structure of chemical species; structural features of liquids, solutions, surfaces, supramolecular systems, nano- and solid materials; and the crystal structure of solids.
