Abstract

<abstract abstract-type="main" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>A range of single‐crystal structures of the type [Pd(cod)(<italic>LL</italic>′‐Bid)]<italic>A</italic>, where <italic>LL</italic>′‐Bid = acetylacetonato (acac), thenoyltrifluoroactetonato (thtfac) and hexafluoroacetylacetonato (hfacac), and <italic>A</italic> = tetrafluoroborate (BF₄⁻) and hexafluorophosphate (PF₆⁻), are reported. The complexes [Pd(cod)(acac)]PF₆ (I), [Pd(cod)(thtfac)]PF₆ (III), [Pd(cod)(thtfac)]BF₄ (IV) and [Pd(cod)(hfacac)]PF₆ (V) are isostructural in the monoclinic space group <italic>P</italic>2₁/<italic>c</italic>. The influence of the variation of the β‐diketonato‐type ligands on the coordination geometry of <italic>cis</italic>, <italic>cis</italic>‐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.</p> </abstract>
