    A 2hJNN intermolecular spin-spin coupling constant (SSCC) of 10.2 ± 0.4 Hz has been measured for the powdered tetrachlorogallate salt of pyridinium solvated by pyridine (pyridine-H +⋯pyridine cation 3). Density Functional Theory (DFT) calculations at the B3LYP/6-311++G(d, p) level reproduced this value and two others reported in the literature for 2hJ intermolecular SSCCs, which were measured for complexes in solution. © 2010 Elsevier Inc.
