“…The remaining coordination site is occupied by the chloro ligand. 3), which fulfill the geometric parameters given in the literature, [30][31][32][33] were found. The Pd-N bond lengths (1.995(5)-2.047(6) Å) are shorter than those found in palladium complexes with edta tetra-alkyl ester ligands (2.098(4)-2.106(7) Å).…”

The reaction of K 2 [PdCl 4 ] with (S,S)-(i-Pr) 2 eddip diester (diisopropyl (S,S)-2,2'-(1,2-ethanediyldiimino)dipropanoate) resulted in {PdCl 2 [(S,S)-(i--Pr) 2 eddip-κ 2 N,N']} (1) and {PdCl[(S,S)-(i-Pr)eddip-κ 2 N,N',κO]}(2) with one hydrolyzed ester group. The compounds were characterized by spectroscopic methods and it was proved that the reaction is diastereoselective ( 1 H-and 13 C-NMR) in the case of 2 (one diastereoisomer of four possible). The structure of 2 was determined by X-ray diffraction analysis, indicating that the product is the (R,R)-N,N' configured isomer. In contrast, the reaction yielding 1 produced two of three possible diastereoisomers. DFT calculations support the formation of two diastereoisomers of 1 and of one diastereoisomer of 2.

“…Indeed, there is a considerable amount of both intra-and intermolecular interactions within the two molecules of (c) ( Table 3). Hydrogen bonding has been used recently to control molecules and ions in the solid state for applications in crystal engineering and supramolecular synthesis [23][24][25].…”

Schiff bases (HL) derived from sulfanilamides or aminobenzothiazoles add to Pd(OAc) 2 to give complexes of the type PdL 2 (1-7) in moderate to excellent yields. Reactions of Schiff bases containing pyrimidine groups, however, gave several products arising from competing coordination of the pyrimidine nitrogen. Palladium complexes and Schiff bases have been investigated as antifungal agents against Aspergillus niger and Aspergillus flavus.

“…Molecules are also linked by weak Pt(1)···N(8′) (3.561 Å) and Cl(1)···Pt(1′) (3.794 Å) interactions. Hydrogen bonding has been used recently to self-assemble related organometallic platinum complexes (41).…”

Five platinum pyridin-2-ylcarboxaldimine complexes of the type cis-[PtCl 2 (2-C 5 H 4 NCH=NR)] (R = CH 2 CH 2 OH (1); R = N(CH 2 CH 2 ) 2 O (2); R = C 6 H 5 (3); R = 1-C 10 H 7 (4); R = (CH 2 ) 8 CH=CH(CH 2 ) 7 CH 3 (5)) were prepared and their in vitro reactivity towards a 20-base pair (single-and double-stranded) DNA determined using nuclease digest studies and RP-HPLC. Variation of the imine functionality allowed for the design of compounds with different physical and chemical properties. Complexes 1 and 3 showed binding to both single-and double-stranded DNA comparable to that of cisplatin (cis-[PtCl 2 (NH 3 ) 2 ]). Crystals of 1 were monoclinic, space group P2(1)/n, a = 9.6612 (15), b = 12.9678 (19), c = 9.7004(13) Å, β = 117.73(3)°, Z = 4. Résumé : On a préparé cinq complexes de pyridin-2-carboxaldimine et de platine du type cis-[PtCl 2 (2-C 5 H 4 NCH=NR)] (R = CH 2 CH 2 OH (1); R = N(CH 2 CH 2 ) 2 O (2); R = C 6 H 5 (3); R = 1-C 10 H 7 (4); R = (CH 2 ) 8 CH=CH(CH 2 ) 7 CH 3 (5)) et, faisant appel à des études de « RP-HPLC » et de digestion par une nucléase, on a évalué leur réactivité in vitro une molécule d'ADN à vingt paires de bases (à simple et à double brin). La variation de la fonction imine a permis de mettre au point des composés ayant des propriétés physiques et chimiques différentes. La fixation des complexes 1 et 3 à l'ADN à simple et à double brin semble être comparable à celle du cisplatine, cis-[PtCl 2 (NH 3 ) 2 ]. Les cristaux du composé 1 sont monocliniques, groupe d'espace P2(1)/n, avec a = 9,6612(15), b = 12,9678(19) et c = 9,7004(13) Å, β = 117,73(3)°et Z = 4.
