[N,N'-Bis(2,3,4-trimeth-oxy-benzyl-idene)-ethane-1,2-diamine-κ(2)N,N']dibromido-mercury(II)
Abstract:
In the title compound, [HgBr(2)(C(22)H(28)N(2)O(6))], the Hg(II) ion is bonded to two Br(-) ions and two N atoms of the chelating Schiff base ligand in a distorted tetra-hedral geometry. The Schiff base ligand adopts an E,E conformation. The dihedral angle between the planes of the two halves of the central N,N'-dimethyl-ethylenediamine part of the ligand is 2.3 (11)°. The crystal studied was twinned by pseudomerohedry [twin law (0-10/-100/00-1)]; the contribution of the minor twin component refined to 0.208 (3).
