title: Crystal and Molecular Structure of Dichloro(ethylenediamine)gold(III) Nitrate: [Au(NH2CH2CH2NH2)Cl2]NO3.
abstract: The gold(III) atom in [Au(NH2CH2CH2NH2) Cl2]NO3is chelated by the ethylenediamine (en) ligand and the approximately square planar geometry is completed by two chloride atoms. Weak Au⋯O and Au⋯Cl contacts are noted above and below the square plane leading to a tetragonally distorted octahedron for the gold(III) center. Extensive charge-assisted hydrogen bonding of the type N-H⋯O leads to the formation of a 2-D array and layers are consolidated into a 3-D network via C-H⋯O and C-H⋯Cl contacts. The compound crystallizes in the orthorhombic space groupPbcawitha= 10.3380(11) Å,b= 8.2105(7) Å,c= 19.625(2) Å, andZ= 8.
