Structure of [C10H10N2][Pr(SO4)2(H2O)2]2, (IIb).
The asymmetric unit of IIb consists of 19 non-hydrogen atoms.
It has one crystallographically independent Pr3þ atoms, two sulfate units, half a molecule of protonated bipyridine molecule, and two coordinated water molecules (Figure S12, Supporting Information).
The Pr3þ ions are coordinated by seven sulfate oxygen and two aqua oxygen forming a PrO9 polyhedra with a distorted tricapped trigonal prism arrangement (Figure S13,
Supporting Information).
The half bipyridine molecule is related to the other half via the C-C bond, which lies on the center of symmetry.
The Pr-O bond distances are in the range of 2.402(2)-2.820(2) Å (av. 2.539 Å).
The O-Pr-O bond angles are in the range 54.65(6)-149.31(6). The selected bond distances are given in Table 3.
