Dichloridobis(methanol-κO)[cis-(±)-2,4,5-tris­(pyridin-2-yl)-2-imidazoline-κ3 N 2,N 3,N 4]ytterbium(III) chloride

In the crystal structure of the title complex, [YbCl2(C18H15N5)(CH3OH)2]Cl, the pseudo-penta­gonal–bipyramidal coordination geometry of the YbIII cation is composed of three N atoms from one cis-(±)-2,4,5-tris­(pyridin-2-yl)imidazoline (HL) ligand, two O atoms from two methanol mol­ecules and two Cl− anions. Chains are formed along [010] through N—H⋯Cl, O—H⋯Cl and O—H⋯N hydrogen bonds

3-Amino­pyridin-1-ium 3-carb­oxy­benzo­ate

In the title organic salt, C5H7N2 +·C8H5O4 −, the carb­oxy­lic group is nearly coplanar with the benzene ring [dihedral angle 1.9 (4)°] whereas the carboxyl­ate group is twisted relative to the benzene ring by 13.6 (4)°. In the crystal, N-H⋯O and O—H⋯O hydrogen bonds connect the components into a three-dimensional framework consisting of stacks of alternating pairs of anions and cations exhibiting π–π stacking inter­actions with centroid–centroid distances in the range 3.676 (2)–3.711 (1) Å. The π–π stacks extend along [110] and [-110]
