摘要：
The crystal and molecular structure of doubly protonated tetraazamacrocyclic complex of gold(III) [Au(C14H24N4)][H3O](ClO4)(4) has been determined. The crystals are monoclinic: a=11.158(2) angstrom, b=8.243(1)angstrom, c=14.756(2) angstrom; beta=98.65(1)degrees, V=1341.8(3)angstrom(3), Z=2, rho(calc)=1.134 g/cm(3), space group P2(1)/n. The structure is built of almost flat centrosymmetrical Au(C14H24N4)](3+) and [H3O](+) cations and [ClO4](-) anions. The gold atom is coordinated with four nitrogen atoms of the ligand forming a flat square. The coordinated ligand is protonated at its gamma-carbon atoms of the two six-membered chelate rings. The Au-N bond lengths are almost identical (the mean value is 1.994 angstrom). The six-membered rings of the complex contain C=N diimine bonds. The [H3O](+), oxonium ion has H-bonds with the oxygen atoms of perchlorate ions.
