Thermodynamic data are reported for the reaction of Lewis bases with mercury(11) thiocyanate in acetonitrile solution. Pyridine, 4-methylpyridine and tetrahydrothiophen form 1 : 1 adducts with adduct formation constants and enthalpies of formation comparable to those with mercury(11) iodide. 1,l0-Phenanthroline, 2,2'-bipyridine and N,N,N',N?-tetramethylethane-1,2-diamine form chelate 1 : 1 adducts, but with enthalpies of formation little larger than that with pyridine. The phosphines, PPh3 and Pbu3, form 1 : 1 and 1 : 2 adducts of much greater stability, though the enthalpies of formation of these adducts are also similar to that with pyridine; Hg(SCN)2PBu3 is dimeric in dilute solution.

The effect of the proximal ligand on the coordination of the nitrite ligand to the heme model systems Fe(Por)(η1-ONO) (Por = meso-tetraarylporphyrinato dianion) was investigated by FTIR and UV-vis spectra in solvent free, low temperature, porous layered solids and by density functional computations. The reaction of the five-coordinate complex Fe(Por)(η1-ONO) with the ether tetrahydrofuran gives a mixture of the O-nitrito and N-nitrito isomers Fe(Por)(THF)(η1-ONO) and Fe(Por)(THF)(NO2), respectively. This observation is in contrast to earlier studies with nitrogen donor Lewis bases where the N-nitrito isomers were clearly the more stable of the six-coordinated complexes. The adduct formation is reversible; the five-coordinate O-nitrito complexes Fe(Por)(η1-ONO) were largely restored upon warming under vacuum pumping.

Enthalpies of complexation of the α,β-unsaturated Lewis bases crotonaldehyde, 1; methyl crotonate, 2; mesityl oxide, 3; and crotononitrile, 4; with each of the Lewis acids SnCl4, TiCl4, SbCl5, and BCl3 were measured in solution in CH2Cl2. The results indicate that while a qualitative agreement exists in the ranking of Lewis acids for each of the Lewis bases, there is only a modest quantitative correlation. Similarly, when compared with an nmr-derived Lewis acid scale, the enthalpies were found to agree with the qualitative ranking of Lewis acids, but exhibited only a poor correlation.
