  The new palladium(II) complex Pd[C5H3N-2,6-(CONPh)(2)](eta(1)-NCMe) (1), prepared from N,N'-diphenyl-2,6-pyridinedicarboxamide and Pd(OAC)(2) in acetonitrile, has been characterized via IR, H-1 NMR and single-crystal X-ray diffraction. In this compound the palladium centre is coordinated to three nitrogen donors of the anionic ligand and to the nitrogen atom of acetonitrile.Moreover, the already known Pd[C5H3N-2,6-(CONCH2CH2Ph)(2)](eta(1)-NCMe) (2) has been studied by H-1 NMR spectrometry and found to readily convert into the macrocyclic tetranuclear species 3, Pd[C5H3N-2,6-(CONCH2CH2Ph)(2)]}4 which has been isolated and characterized by IR, H-1 and C-13 H-1-(NMR)-N-13, H-1-C-13 HETCOR and mass spectrometry, as well as by single-crystal X-ray diffraction. In 3, of S-4 symmetry, each palladium atom is coordinated to the three nitrogen atoms of the anionic ligand, while the fourth coordination position is occupied by the amidato oxygen atom of an adjacent unit. This structure is apparently maintained in CDCl3 solution. The substitution reactions of acetonitrile in 2 with the ligands EEt2 (E = S, Se) afford Pd[C5H3N-2,6-(CONCH,CH,Ph)(2)](EEt2) (4, E = S; 5, E = Se); these products can also be obtained by the addition of EEt2 to 3, as shown by means of H-1- and, in the case of E = Se, Se-77H-1} NMR spectroscopy in CDCl3 solution. These results show that the Pd-O bonds of the tetranuclear species are readily broken by weakly coordinating ligands such as acetonitrile and diethylchalcogenides. Nevertheless, we are dealing with equilibrium reactions and, in some solvents, 3 can be obtained from 2, 4 or 5 being favoured by its low solubility. (c) 2005 Elsevier B.V. All rights reserved.
