Assembling novel Cd(II) complexes with multidentate nitrogen donor ligands obtained in situ from the system: zerovalent copper, cadmium oxide, 1-hydroxymethyl-3,5-dimethylpyrazole and ammonium thiocyanate.

A novel 3D coordination polymer [Cd2(L(1))(2)(SCN)(4)(MeOH)(2)](n) (1) and monomeric [Cd(NCS)(2)L(2)] (2) (L(1) = urotropine, L(2) = tris(1-(3,5-dimethylpyrazolylmethyl))amine) have been prepared in a one-pot synthesis using 1-hydroxymethyl-3,5-dimethylpyrazole as the starting ligand. The most prominent feature is the formation in situ of the organic compounds: urotropine and scorpionate-tripodal ligands.
