A dynamic combinatorial process has allowed the isolation of four new compounds produced in the direct solvothermal reactions of pyrimidine-2(1H)-thione (pymSH) or bis(2-pyrimidyl)disulfide (pym2S2) with nickel halides (chloride, bromide). The in situ cleavage of S–S, S–C(sp2) bonds generates the pyrimidinesulfide (pym2S) and pyrimidinetrisulfide (pym2S3) ligands and the formation of nickel complexes. In all cases, the in situ generated molecules behave as chelating terminal ligands, therefore no evidence of their potential bridging capability is available for Ni(II). The magnetic properties of the compounds indicate the presence of moderate antiferromagnetic interactions that become more intense as the number of bridging halides increases.
