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

−, 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]
