A range of single‐crystal structures of the type [Pd(cod)( LL ′‐Bid)] A , where LL ′‐Bid = acetylacetonato (acac), thenoyltrifluoroactetonato (thtfac) and hexafluoroacetylacetonato (hfacac), and A = tetrafluoroborate (BF 4 − ) and hexafluorophosphate (PF 6 − ), are reported. The complexes [Pd(cod)(acac)]PF 6 (I), [Pd(cod)(thtfac)]PF 6 (III), [Pd(cod)(thtfac)]BF 4 (IV) and [Pd(cod)(hfacac)]PF 6 (V) are isostructural in the monoclinic space group P 2 1 / c . The influence of the variation of the β‐diketonato‐type ligands on the coordination geometry of cis , cis ‐1,5‐cycloocta‐1,5‐diene (cod) was investigated and found that no significant changes to the Pd—C and C=C bond distances were observed. The `Venus fly trap' parameters vary by 7.8° for the `jaw' angle (ψ), while the `bite' angle (χ) remains virtually constant.
