Crystal Structure of 2,6-Dioxa-14,18-diazatricyclo-[18.4.0.07,12]-tetracosa-7,9,11,20,22,24(1)-hexsaene-diacetatopalladium(II)

Abstract

In the title complex, C<inf>24</inf>H<inf>32</inf>N<inf>2</inf>O<inf>6</inf>Pd, Pd(II) ion, is coordinated bidentately to N atoms of the macroring and monodentately to O atoms of the acetate ligands, in a square-planar geometry. The etheric oxygens of the macroring are not bonded to the metal ion, but are interestingly bonded to each hydrogen of the benzylic CH<inf>2</inf> groups. On the other hand, beside of the intramolecular C-H···O bonds, the strong intramolecular N-H···O hydrogen bonds, between the two acetate oxygens and N atoms of the macroring, also contribute to stabilization of the molecular structure. It belongs to the space group Pbca with cell parameters a = 14.1507(6), b = 16.9866(7), c = 20.4128(11)Å. 2006 © The Japan Society for Analytical Chemistry.
