The new mixed metal assembly [Ni(phen)3][Cu(H-1pap)]2(NO3) · 8 H2O (2) (H2pap = CH3- C(=NO H)-C(O )-NH-(CH2)3-NH-C(O )-C(=NOH)-CH3) was obtained by co-crystallisation of [Li(H2O)4][Cu(H-1pap)] · 2 H2O (1) and tris(1,10-phenanthroline)nickel(II) nitrate and studied by means of X-ray crystallography (triclinic, space group P1, a = 13.471(3), b = 13.641(3), c = 15.401(3) Å, α = 108.21(3), β = 97.73(3), γ = 107.74(3)°, V = 2476.6(9) Å , Z = 2 ,R1 = 0.0677 for 4672 unique reflections with I > 2σ(I)). The assembly indicates a network structure and consists of isolated cationic and anionic modules (octahedral [Ni(phen)3]2+and square-planar [Cu(H-1pap)]-), non-coordinated nitrate anions and solvating water molecules. The elements of the crystal structure are linked by interactions of different types: by an extended system of H bonds, stacking interactions between aromatic rings, long apical Cu-N contacts and specific π-π interaction between a deprotonated oxime group of the complex anion and a phenanthroline ligand |
