Molecular design and the optimum synthetic route of the compounds with multi-pyrazole and its derivatives and the potential application in antibacterial agents

Molecular design and efficient synthetic procedures have been developed for pyrazole and its derivatives with different linkers. In particular, twelve compounds with -I or -NO2 substituted groups on the pyrazole ring were synthesized for the fi

Dinuclear species versus zigzag or helical polymers in palladium, zinc, and copper complexes with ditopic bis(pyrazolyl)methane ligands

Two new all-nitrogen donor ditopic ligands, namely, p-bis[bis(pyrazol-1-yl) methyl]biphenyl (L3) and p-bis[bis(3,5-dimethylpyrazol-1-yl)methyl]biphenyl (L4), have been synthesized. Their coordination chemistry, along with that of the previously described ligands p-bis[bis(pyrazol-1-yl)methyl]benzene (L1) and p-bis[bis(3,5-dimethylpyrazol-1-yl)methyl]benzene (L2), has been explored with different metallic fragments. The reactions of L1-L4 with PdCl 2(PhCN)2, Pd(OAc)2 and Zn(NO3) 2 led to the formation of dinuclear species with anti orientation of the metallic fragments and bis(bidentate) chelation of the coordinated ligands. The reactions of L1 or L3 with Cu(OAc)2 produced zigzag polymers with Cu2(OAc)4 paddle-wheel units alternating with ligands that coordinate through one pyrazolyl ring at each end. The reaction between L3 and [Cu(CH3CN)4][BF4] leads to a helical racemic coordination polymer. The presence of methyl groups on the pyrazolyl rings and the geometry of the metal centres influence the parameters of the metallacycles formed by chelate coordination of the ligands. The discrete molecules and the polymers organize to give three-dimensional structures through different noncovalent interactions including hydrogen bonding, CH-π, anion-π and π-π interactions that are influenced by the presence or absence of methyl groups on the pyrazolyl rings. Four all-nitrogen donor ditopic ligands with bis(pyrazolyl)methane units are synthesized. With palladium or zinc fragments, dinuclear species are obtained, whereas with Cu(OAc) 2, zigzag polymers with paddle-wheel units form. Helical racemic polymers are obtained with CuI centres. Noncovalent interactions play an important role in the shape of the molecules and in their supramolecular structures. Copyright
