Synthese, Strukturen und X‐/Q‐Band‐EPR‐Untersuchungen von N,N‐Diethyl‐N′‐3,5‐di(trifluormethyl)benzoylthioureato‐Komplexen des CuII, NiII und PdII sowie EPR‐spektroskopische Charakterisierung eines CuII‐CuII‐Dimers

Abstract: Die Synthese und die Kristallstrukturen des Liganden N,N‐Diethyl‐N′‐3,5‐di(trifluormethyl)benzoylthioharnstoff HEt2dtfmbtu sowie dessen NiII‐ und PdII‐Komplexes werden berichtet. Der Ligand koordiniert zweizähnig unter Bildung von Bischelaten. Der NiII‐ und der PdII‐Komplex sind isostrukturell. Der ebenfalls hergestellte CuII‐Komplex konnte nicht strukturell charakterisiert werden. Die Präparation diamagnetisch verdünnter, für EPR‐spektroskopische Untersuchungen geeigneter Pulverproben vom Typ Cu/Ni(Et2dtfmbtu… Show more

“…Its molecular structure ( Fig. 1) is closely related to that of the 3,5-di(trifluoromethyl)-substituted compound (Kampf et al, 2004). Bond lengths and angles of the thiourea group agree well with those expected from other thiourea compounds (Arslan et al, 2006) and need not be discussed further.…”

“…The ORTEP diagram of title complex is shown in Figure with atom numbering scheme Selected bond lengths, bond angles and torsion angles are summarized in Table S1 (Supporting Information). The platinum(II) ion is coordinated by two phosphorus atoms of two bulky triphenylphosphine ligands, and the oxygen and sulfur atoms of one bidentate L 1 ligand forming a four‐coordinate cis ‐planar geometry as occurs in the structural chemistry of bis‐chelates benzoylthioureas with d 8 or d 9 ions . A PF 6 – group acts as outer‐sphere anion of the complex.…”

“…Examples for such compounds include bis(chelates) with the divalent transition metal ions Cu 2+ , Ni 2+ , Pd 2+ , Pt 2+ , Zn 2+ and Cd 2+ . [1][2][3][4][5][6][7][8][9][10] There are also examples of tris(chelates) with the trivalent metal ions Fe 3+ , Co 3+ and In 3+ . [11][12][13] Amongst the main group elements, bis(chelates) containing lead(II) have been of recent interest as single-source precursors for various PbSe nanomaterials.…”
