Synthesis and crystallographic characterization of cationic Pd(II) complexes containing bis(diphenylthiophosphinyl)methane

Mono‐ and dinuclear oxime palladacycles bearing diphosphine ligands: An unusual coordination mode for dppe

“…The presence of ClO 4 − group was evidenced by two bands in the regions 1100 and 622 cm −1 . These values are consistent with the literature values . The band at 850–950 cm −1 characteristic of all complexes is assigned to PC vibration.…”

“…While the presence of methinic proton in complex 3 is evidenced as a triplet at 4.8 ppm with 2 J P,H = 12.50 Hz. This is in good agreement with the value observed for similar phosphine complexes . The 13 C{ 1 H} NMR spectra of all complexes show two peaks at around 13 and 30 ppm, which are assigned to CH 3 and PCH 2 , respectively.…”

Bis[bis(diphenylthiophosphinyl)amido-κ2S,S′]platinum(II)

“…In the Pt1/S1/P1/N1/P4/S4 ring, the Pt1-S1-P1-N1 and Pt1-S4-P4-N1 torsion angles are -57.12 (13)° and -51.12 (14)°, respectively, with ring puckering parameters of θ= 89.31 (11)° and Φ= 287.34 (13)°. This supports a twist-boat conformation (Cremer & Pople,1975 [Yanar et al, 2007;İrişli & Yanar, 2006]. The observed P1-S1, P2-S2, P3-S3 and P4-S4 lengths [2.0279 (12) Å, 2.0332 (13) Å, 2.0327 (14)Å and 2.0304 (12) Å] are closer to single bond than double bond lengths (Berry et al, 1988).…”
