Abstract [en]

Two bis(quadridentate) eight-coordinate zirconium complexes, Zr(5-Cldse)(2) (1) [5-Cldse = N,N'-di(5-chlorosalicylidene)ethylenediamino] and Zr(pida)(2) (2) [pida = N-(2-pyridylmethyl) iminodiacetato], have been prepared and crystallographically characterized. A distorted dodecahedron of N4O4 atoms has been found for the zirconium(IV) center of complexes (1) and (2). A network is constructed in the crystalline state of (1) by crisscross intermolecular Cl...Cl contacts (3.45 and 3.43 angstrom), which are shorter than the sum of spherical van der Waals radii (3.50 angstrom).
