| Abstract | • Introduction Mild template synthesis was shown to occur in the M(II)dithiooxamideformaldehyde and in the M(II)dithiooxamideacetone triple systems (M= Ni, Cu) at the contact of corresponding metal(II)hexacyanoferrate(II) gelatin-immobilized matrices (M2[Fe(CN)6] -GIM) with aqueous-alkaline solutions containing dithiooxamide and formaldehyde or acetone [1,2]. Dithiooxamide and formaldehyde or acetone were ligand synthons in such a process. We would like to report in this paper that we had found template synthesis proceeding in the triple M(II) -dithiooxamide -glyoxal systems in the M2[Fe(CN)6]-GIM where Μ is Co, Ni or Cu. • Experimental Cobalt(II)-, nickel(II)and copper(II) metalhexacyanoferrate(II) GIMs were synthesized as described in [3-5]. Synthesis of CoC6S4N402H7. This synthesis occurs on contact of Co2[Fe(CN)6] GIM with alkaline solutions (pH=ll-12) containing dithiooxamide and glyoxal. The concentration of cobalt(II) hexacyanoferrate(II) in the matrix was 0.1-2.0 mol dm", the concentration of dithiooxamide and glyoxal in a solution was (3.0 10" -5.0 10") mol dm" and (6.0 10' -1.0 10") mol dm', respectively. The duration of the process was 10-12 min at 18-20°C. The matrix obtained was treated with the solution of proteolytic enzyme Bazillus mesentericus, as a result gelatin binding of matrix was split into soluble low mol. wt. compounds whereas coordination compound synthesized was precipitated and then isolated from a mother liquor. Finally, the substance isolated from GIM was washed with distilled water, ethanol and dried at room temperature. Found (%): Co, 16.8; C, 20.4; S 36.1; N, 15.8; O, 8.6; H, 2.2. CoC6S4N402H7, calc.
