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, C24H32N2O6Pd, 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 CH2 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.
