Abstract

AbstractThe weak intermolecular noncovalent interactions in the solvatecis-[PtCl2(C2H5CN)2]·CHCl3were studied by XRD and DFT methods. Special attention was paid to a chloroform molecule as a potential donor of both hydrogen and halogen bonds. On the one hand, the H atom of chloroform links two Cl atoms ofcis-[PtCl2(C2H5CN)2] (Hchloroform–Clcomplex(2.660 Å, 2.811 Å)), and on the other side, the weak Clchloroform–Clcomplex(3.247 and 3.497 Å) interactions were found. According to DFT calculation, only the Hchloroform–Clcomplex(2.660 and 2.811 Å) and Clchloroform–Clcomplex(3.247 Å) interactions can be classified as weak noncovalent bonds, whereas the contacts Clchloroform–Cnitrile(3.391 Å) and Clchloroform–Clcomplex(3.497 Å) are due to the crystal packing effect.
