In the title compound, [Ag3(C12H12N2O2)4](PF6)3, one AgI ion, lying on a twofold rotation axis, is coordinated by four N atoms from four 1,3-bis(4,5-dihydro-1,3-oxazol-2-yl)benzene (L) ligands in a distorted tetrahedral geometry and the other AgI ion is coordinated by two N atoms from two L ligands in a bent arrangement [N—Ag—N = 169.03 (17)°]. Two L ligands adopt a syn conformation, while the other two adopt an anti conformation. They bridge adjacent AgI ions, forming a trinuclear complex. One of the PF6− anions is half-occupied, with the P atom located on a twofold rotation axis. The PF6− anions link the complex molecules via AgF interactions [2.80 (2) and 2.85 (2) Å] into a polymeric chain along [100].

The title compound, {[NiCl2(C5H6N2)(C3H7NO)]·C3H7NO}n, is a two-dimensional polymer in which the NiII atom is coordinated by two N atoms from two 3-aminopyridine ligands, one O atom from a dimethylformamide (DMF) group, one terminal Cl and two bridging Cl atoms in a distorted octahedral geometry. The NiII atoms are bridged by the 3-aminopyridine ligands [NiN = 6.7048 (3) Å] and Cl− atoms [NiN = 3.5698 (3) Å], forming (4,4) two-dimensional nets. The DMF solvent molecule and the non-bridged Cl− ions participate in N—HO and N—HCl hydrogen bonds with the amino groups.
