“…The dihedral angle between the imidazole ring and the ligand plane is 47°. Similar trans-dichlorobis(imidazole)-Pd(II)( not counting benzimidazole) complexes have been reported previously [2][3][4][5][6][7][8][9][10][11][12][13]. However, complexes involving 1,2-disubstituted imidazole ligands seem to be rare [14][15][16][17].…”

Dedicated to Professor AndreÂ E. Merbach on the occasion of his 65th birthdayThe two known Me-and allyl-substituted 1H-imidazol-3-ium bromides 1 and 2, respectively, were converted to the corresponding BF À 4 and BPh À 4 salts 3 ± 6 (Scheme 1). Compounds 3 and 4 were liquids at ambient temperature. Reaction of 1 or 2 with [PdCl 2 ] afforded the corresponding 2 : 1 imidazolium/metal complexes 7 and 8. The latter complex, melting at 588, can be regarded as a true ionic liquid. Attempts to polymerise 7 by radical promotion (AIBN) were unsuccessful, but resulted in the centrosymmetric 2 : 1 complex 9. The allyl group of 1 could be arylated (giving rise to 10) or hydrogenated (at 100 bar H 2 pressure). The solidstate structures of compounds 5 ± 7 and 9 were solved by means of single-crystal X-ray analyses (Figs. 1 ± 4).Introduction. ± Room-temperature ionic liquids have received considerable attention as alternative solvents for a wide range of applications, in particular as reaction media for homogeneous, heterogeneous, and enzymatic catalysis [1]. Ionic liquids that incorporate functional groups are becoming more and more important, since imparting specific chemical properties to the ionic liquid could lead to highly specific roles in synthesis and catalysis unparalleled by more-generic systems. It is interesting to note that the first liquid alkene-or allyl-substituted 1 ) imidazolium salts were reported as early as 1971 [24]. However, at that time, the

“…The planes of guanine fragments are significantly rotated relative to the plane perpendicular to the direction determined by the practically linear grouping Cl1-Pd1-Cl2. The torsion angles Cl2-Pd1-N19-C14 of 57.05 • and Cl2-Pd1-N9-C4 of −60.32 • differ greatly from 90 • as in similar compounds [41][42][43]. However, in this case, the planes of both ligands almost coincide (angle (plane normal-plane normal): 3.000 • ), which is obviously due to H-bonding with the outer-sphere chloride ion.…”

“…Previously, only a few compounds similar to ours were described. Complexes are described in the literature in which the Pd atom is bound by a Pd-N bond with an organic ligand [41][42][43][44]. But in almost all works, electrically neutral complexes are obtained.…”

The aim of the work was to synthesize new perspective compounds of palladium and platinum with nitrogenous bases (guanine), promising for use in biomedicine and catalysis. The article describes the synthesis of new [PdCl2(HGua)2]Cl2·H2O and [PtCl5(HGua)]·2H2O compounds using wet chemistry methods. The structure of the obtained single crystals was established by the method of single crystal X-ray diffraction. The complexes have an M-N bond, and the organic ligand is included in the first coordination sphere. The analysis of Hirshfeld surfaces for the obtained complexes and their analogues for the analysis of intermolecular interactions was carried out. In the palladium complex we obtained, π-halogen and π-stacking interactions were found; in analogues, such interactions were not found. π-halogen and halogen interactions were found in structure of platinum complex and its analogues.
