Halogen Bonding Synthon Modularity in Coordination Compounds

Abstract

In this Communication, the modulation of halogen bonding synthons in the crystal structure of [HgBr 2 (L 3,4-diCl )] from [HgBr 2 (L 3-Cl) ] and [HgBr 2 (L 4-Cl )], as single components, where L is a N -(chlorinatedphenyl)-2-pyrazinecarboxamide ligand, has been investigated. Reviewing the crystal packing reveals that Cl···N and Cl···Br halogen bonds stood as a remembrance of the crystal structures of single components in the packing of [HgBr 2 (L 3,4-diCl )].
