Abstract
Abstract
Dichloro[3-(pyridin-2-yl)-1,2,4-triazinone]Pd(II) undergoes oxidative C–C coupling reaction with cyclopentanone and cyclohexanone at 110°C to yield the respective Pd complexes, chloro[1-(4-chlorophenyl)-5-(2-hydroxycyclopent-1-enyl)-3-(pyridin-2-yl)-1,2,4-triazin-6(1H)-one]palladium(II) (3) and chloro[1-(4-chlorophenyl)-5-(2-hydroxycyclohex-1-enyl)-3-(pyridin-2-yl)-1,2,4-triazin-6(1H)-one]palladium(II) (4). The structures of both complexes are supported by spectral data and confirmed by single-crystal X-ray crystallography. The molecules 3 and 4 stack to form tunnel structures, whilst the geometry around the palladium ion is square planar.
