Rigid Covalent Atomic Groups in Precrystallization Phase for Hg-containing Compounds

Victor V. Atuchin, Stanislav V. Borisov, Svetlana A. Magarill, and Natalia V. Pervulhina

Abstract—During crystal chemical analysis of about fifty mercury-containing compounds the atomic groups same from structure to structure were found. Such atomic groups, namely [Hg4O] oxo-centered tetrahedron and r-octahedron [Hg6O2], are covalently bonded. Quantum-chemical calculations prove stability of these ‘rigid’ atomic groups that are assumed to be formed in the beginning of crystallization. Thus, mechanism of crystallization proposed includes mutual arrangement of isolated or joint-like linked rigid atomic groups and finally their regular packing. At that point symmetry of these rigid atomic groups becomes subgroup of space group of the whole structure.

Index Terms—Crystal structure, mercury, minerals, coordination.
