Аннотация: 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.
