Three new heterobimetallic cyanide-bridged complexes, {[Ni(L¹)][Ag(CN)₂]}[Ag(CN)₂] ·2H₂O (2), {[Mn(L¹)][Ag(CN)₂]} · 1.5H₂O (3) and {[Mn(L³)(H₂O)]₂[Ag(CN)₂]}ClO₄ · 2H₂O (4) (L¹ =2,7,12-trimethyl-3,7,11,17-tetraazabicyclo[11.3.1]heptadeca-1(17),13,15-triene; L² = N,N’-1,3-propylenebis(5-chlorosalicylideneiminate); L³ = N,N’-1,2-propylene-bis(5-bromosalicylideneiminate)), have been assembled using for the first time a new polyaza macrocycle nickel(II) compound [Ni(L¹)](ClO₄)₂(1), or Schiff-base manganese(III) compounds and K[Ag(CN)₂]. Single crystal X-ray diffraction analysis reveals that complexes 2 and 3 can be characterized as one-dimensional cationic and neutral single chain structure, respectively. Complex 3 forms a three-dimensional network via weak inter-chainAg…Aginteractions. Complex 4 belongs to a cyanide-bridged bimetallic sandwich-like cationic trinuclear structure containing Mn₂Ag core with free ClO^-₄ as a counter anion, indicating that the Schiff-base ligand has an obvious influence on the structure of the cyanide-bridged complexes formed. Investigation of the magnetic susceptibilities of the cyanide-bridged Ag-Ni(II)/Mn(III) complexes showed the weak anti-ferromagnetic interaction between neighboring paramagnetic Ni(II) or Mn(III) ions bridged by the long NC-Ag-CN unit. From the best-fit of the magnetic susceptibility data of complexes 2 and 4 the magnetic coupling constant was determined to be J = −0.51 and −0.78 cm^-1,respectively.
