Kompleksi rodija(III) s 2-(2\u27-piridil)kinolinom. Priprava i spektroskopska obilježja

Rhodium(III) complexes containing 2-(2\u27-pyridyl)quinoline (PQ) were prepared by the reaction of RhCl3 · 6H2O and PQ in 1:2 mole ratio followed by addition of an excess of sodium salts to the reaction mixture. The new complexes cis-[RhX2(PQ)2]Y (where X = NO2 –, Y = PF6 –; X = SCN– or NO3 –, Y = Cl–; X = Y = I–) and cis-[Rh(N3)2(H2O)2(PQ)]PF6 were characterized by elemental analysis, conductivity measurements, IR, 1H and 13C NMR.Reakcijom RhCl3 · 6H2O i 2-(2\u27-piridil)kinolina (PQ) u molnom omjeru 1:2 uz dodatak odgovarajuće natrijeve soli priređeni su novi kompleksi rodija(III): cis-[RhX2(PQ)2]Y(X = NO2 –, Y = PF6 –; X = SCN– ili NO3, Y = Cl–; X = Y = I–) i cis-[Rh(N3)2(H2O)2(PQ)]PF6. Spojevi su opisani temeljem elementarnih analiza, mjerenja molarne vodljivosti te infracrvene, 1H NMR i 13C NMR spektroskopije

Supramolecular Interactions Involved in the Solid State Structure of N,N\u27-[bis(pyridin-2-yl)formylidene]ethane-1,2-diamine

The structure of the symmetrical Schiff base, N,N\u27-[bis(pyridin-2-yl)formylidene]ethane-1,2-diamine (bpfd) has been characterized by single crystal X-ray diffraction. The non-covalent supramolecular chemistry involved in the crystal structure of this ligand has been carefully investigated. The structure adopted different motifs of nitrogen-hydrogen interactions that led to the formation of centrosymmetric dimers. In addition, edge-edge and face-face nitrogen-nitrogen interactions were ob-served and reported. The Schiff base (bpfd) ligand crystallizes in a monoclinic space group C12/c1 with a = 19.128(2) Å; b = 5.8776(6) Å; c = 13.1403(15) Å; α = 90o; β = 121.970o(4); γ = 90o and z = 4. This structure is an example of compounds with many symmetry-independent molecules in the asymmetric unit cell (Z > 2)
