  摘要：

  The coordination geometry about the palladium(II) ion in [PdCl2{Ph2P(CH2)(2)NH2}] is distorted square planar. Individual atoms are displaced from the PdCl2PN coordination plane by no more than 0.094 Angstrom, while inplane distortion of the bond angles at the metal atom is more marked. The greater trans influence of phosphine over amine is reflected in the mean Pd-Cl bond lengths of 2.383 Angstrom, trans to P, and 2.293 Angstrom, trans to N.

  Complexes of functionalised phosphine ligands. Part 1. Complexes of Fe^III, Co^III, Ni^IIand Re^Vwith tridentate Schiff bases having PNO, NNO and NNS donor sets. Crystal structures of 2-(Ph₂PC₆H₄NCH)C₆H₄OH and [Co{2-(Ph₂PC₆H₄CHN)C₆H₄O}₂][PF₆]

  摘要：

  The Schiff bases 2-[Ph(2)P(CH2)(n)N=CH] C6H4OH (n = 3, HL(1) or 2 HL(2)), 2-(RCH=N)C6H3(OH)X-4 (R = 2-Ph(2)PC(6)H(4), X = H HL(3); R = 2-C5H4N, X = H HL(4); R = 2-C5H4N. X = Cl HL(5)) were synthesised from the appropriate amine and aldehyde. On deprotonation these all functioned as tridentate monoanionic ligands to give complexes [FeL(2)](+) and [CoL(2)]+ with Fe-III and Co-III and neutral complexes of stoichiometry NiL(2) with Ni-II. The iron complexes were examined by Mossbauer spectroscopy which indicated the presence of two iron sites in [FeL(2)(1)](+) with a spin-state equilibrium dependent on both temperature and the counter ion. The complex [FeL(2)(3)](+) showed a single iron site, again with a spin state dependent on counter ion and temperature. The crystal structures of HL(3) and [CoL(2)(3)](+) have been determined. The distortions in free HL(3) predispose it for co-ordination in a fac geometry to the Co with cis-PPh(2) groups, and the changes occurring on co-ordination are discussed in detail. Reaction of RCHO (R = 2-Ph(2)PC(6)H(4) or 2-C5H4N) with 2-aminobenzenethiol gave stable thiazoles RCHNHC(6)H(4)S-2 which did not ring open to give tridentate ligands even on reaction with base and/or metal ions.
