چکیده
there has been a considerable interest in platinum group metal complexes of thiaoxa-donor macrocycles because of their unusual properties. 1 As an extension of our studies involving mixed-donor cyclic 2a and acyclic 2b ligands incorporating thiaoxa mixed-donors, we became interested in exploring their coordination chemistry of platinum group metal ions. The S2O-donor macrocycle of the title complexes,

Crystal structure of 6-oxa-3,9-dithiabicyclo[9.2.2]pentadeca-1(15),11,13-triene.
The structure of an S2O mixed-donor macrocycle incorporating para-substituted xylyl subunit was characterized by a single crystal X-ray analysis. The crystal structure shows an exo-dentate orientation of sulfur and oxygen donor atoms due to the fully stretched aliphatic ring conformation. Thus all of torsional angles between donor atoms are arranged anti and S...S distance in a ring is 6.764(1)...
متن کاملCOMPLEXES OF LEAD (II)*: CRYSTAL STRUCTURES OF L2Pb (NO,), AND L2Pb(SCN), L=Z(AMINOMETHYL) PYRIDINE
The reactions of Pb(N0 ) and Pb(SCN)2 with 2-(aminomethy1)pyridine (C H N = L) yielded colourless crystals of L Pb(N0 ) ( I ) and L Pb(SCN) , (2), respectively. Their structures were determined by X-ray crystallography. Crystal data: 1, monoclinic, P2 /c, a = 9.263 (4) ?, b = 7.783 (2) ?, c = 6.692 (3) ?, ? = 101.26 (2)?, Z = 2, Mo K?, 1540 observed (I > 2.5 ?(I) data (22 ? C), R = 0...
متن کاملPalladium(II) Complexes with Benzoxazol-2-ylidene Ligands: Crystal Structures of trans-Chloro(benzoxazol-2-ylidene)- bis(triphenylphosphine)palladium(II) Chloride and cis-Diiodo(benzoxazol-2-ylidene)(triphenylphosphine)palladium(II)
The palladium(II) complexes trans-[PdCl(L)(PPh3)2]Cl, 5, and cis-[PdI2(L)PPh3], 7, (L = benzoxazol-2-ylidene) have been synthesized by treatment of the complexes trans-[PdX2(PPh3)2] (4: X = Cl, 6: X = I) with 2-(trimethylsiloxy)phenyl isocyanide 1, and subsequent hydrolysis of the Si-O bond. The crystal structures of 5 and 7∗CH2Cl2 were established by X-ray diffraction. NMR and IR studies indic...
