Trichloro­[μ-2,2,N-tris­(2-pyridylmethyl­amino)acetamido]dizinc(II)

The title compound, [Zn₂(C₂₀H₂₀N₅O)Cl₃], was prepared from the multidentate ligand 2-[bis­(pyridin-2-ylmeth­yl)amino]-N-(pyridin-2-ylmeth­yl)acetamide and zinc(II) chloride. The deprotonated ligand bridges the two Zn^II ions, coordinating to one in a tripodal fashion through the amide O and three N atoms, and to the second as a bidentate chelate through the amide and one pyridyl N atoms. Cl⁻ anions complete the distorted trigonal–bipyramidal coordination for one Zn^II ion and a distorted tetra­hedral arrangement around the other.

Special details

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
