  • Title: Dichlorido{N-[1-(2-pyrid-yl)ethyl-idene]ethane-1,2-diamine}copper(II).
    Author: Wang Q, Bi CF, Wang DQ, Fan YH.
    Journal: Acta Crystallogr Sect E Struct Rep Online; 2009 Mar 25; 65(Pt 4):m439. PubMed ID: 21582376.
    Abstract:
    The title complex, [CuCl(2)(C(9)H(13)N(3))], is mononuclear and contains a five-coordinate Cu(II) atom. The geometry of the Cu(II) atom can be described as tetra-gonal-pyramidal derived from the calculation of the value τ = 0.102. The three N atoms of the pyridine and ethane-1,2-diamine ligands and one Cl atom belong to the basal plane and the other Cl atom represents the axial position of the pyramid. The Cu atom is displaced by 0.2599 (2) Å from the basal plane towards the axial Cl atom. In the crystal, mol-ecules are linked into chains by inter-molecular N-H⋯Cl and C-H⋯Cl hydrogen bonds.
