Abstract

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.

一个简单化合物的隐藏复杂性：四核铂（II）醋酸酯Pt4（OCOMe）的意外多态性

多态是铂族配合物中罕见的现象。令人惊讶的是，我们发现了一个相对简单的化合物，铂（II）醋酸酯Pt4(OCOMe)8(2)(单斜C2/c(2)，单斜P21/c（3)和四方P43212(4)）的新的单斜晶体修饰（C2/c）。利用同步辐射x射线源，采用单晶x射线衍射（SC-XRD）对该晶型进行了结构鉴定。通过Hirshfeld表面分析2的分子间相互作用，并与另一种已知的多晶型-单斜晶型（P21/c, 3）和四方晶型（P43212, 4）进行比较，以及对包装基序的分析，揭示了弱相互作用对其形成的作用。
