Title: Crystal structures of ethylenediaminemercury(II) dibromide and diiodide
Abstract: Abstract The crystal structures of the two title compounds were determined by X-ray structure analysis. Hg(C 2 H 8 N 2 )Br 2 (1) crystallizes in the orthorhombic system, space group Pbam , with a = 7.624(3), b = 10.143(4), c = 4.504(2) Å, Z = 2. The structure was refined to R = 0.042 using 462 independent reflections. Hg(C 2 H 8 N 2 )I 2 (2) is triclinic, space group P [unk], with a = 9.427(2), b = 6.959(4), c = 6.838(1) Å, α = 106.93(2), β = 83.57(2), γ = 90.03(1)°, Z = 2. The structure was refined to R = 0.045 using 1860 unique reflections. Both structures are built up of infinite chains with ethylenediamine being a centrosymmetrical bridging ligand. In (1) Hg is bonded to two N atoms at 2.19(2) Å and approached by four Br atoms at 3.012(2) Å forming a distorted octahedron. In (2) Hg is bonded to two N atoms [2.35(1) and 2.34(1) Å] and two I atoms [2.691(1) and 2.740(2) Å] forming a distorted tetrahedron.
