N–H⋯O and N–H⋯Cl supported 1D chains of heterobimetallic CuII/NiII–SnIV cocrystals

Abstract

The 1D supramolecular chain of the NH₃⁺–C₂H₄–NH₃⁺·[SnCl₆]²⁻ adduct, supported by N–H⋯Cl bonds, is entrapped by mononuclear Cu^II or Ni^II complexes via strong N–H⋯O interactions in the 1D chain of heterobimetallic Cu₂Sn or Ni₂Sn cocrystals (1–4).
