Reactions of mixtures between Ag(NO3) and alkaline earth nitrates with the bifunctional ligand 2,2'-{1,2-phenylenebis[oxyacetyl(N,N-diethylthiourea)]}, H2Lcat, give {2}-metallacoronates of the composition {M subset of [Ag-2(L-cat)(2)]} (M = Ca2+, Sr2+, or Ba2+). The trinuclear assemblies show further aggregation in the solid state, where they establish dimeric or polymeric entities stabilized by weak AgN(amide) interactions. Discrete {2}-metallacryptate species {M subset of [Hg-2(L-cat)(3)]} (M = Sr2+ or Ba2+) result from similar reactions between H2Lcat, Hg(NO3)(2), and strontium nitrate or barium nitrate. The complexes contain Hg-II ions in an uncommon distorted trigonal-bipyramidal environment with a S3O2 coordination sphere. The central alkaline earth ions are mainly bonded by the six carbonyl oxygen atoms of the three organic ligands.
