Dinuclear Complexes Derivatives of N,N′-Ethylenebis(2-hydroxyacetophenoneimine)-(mesalen) and 1,3-Bis-(2-hydroxyphenyl)-1,3-propanedione (bhppH3). The Crystal and Molecular Structure of Cu(mesalen)Zn(bhppH2)2

Dimeric, Two‐Dimensional and Metal‐Centered Rectangular Heterometallic CuII–AgI/CdII/BaII Systems Derived from a Single Compartmental Ligand

“…As already mentioned, hundreds of heterometallic compounds were reported from single‐ or double‐compartmental acyclic Schiff base ligands (the types of single‐compartmental and double‐compartmental ligands have already been mentioned). Most of these compounds are of the following types: (i) Dinuclear;‐,,,‐,‐ (ii) Trinuclear;‐,‐,,,‐,, (iii) Dinuclear based clusters or polymers;,,,,,,,,,‐,, (iv) Trinuclear based clusters or polymers;,,,,, (v) Cocrystals of dinuclear or trinuclear units and mononuclear units ,,,,. In some rare cases, tetrametallic MCu II 3 ‘Stars’ (M=Cd II , Zn II , Cu II , Ni II , Mn II , Na I ) which are metal‐centered triangles or ‘Stars’, have been stabilized ,,,.…”

A Brief Review on Homo-/Hetero-nuclear Co-ordination Compounds Derived from Some Single Compartmentl Acyclic Schiff Base Ligands having N-,O-Donor Centres

“…Copper(II)/nickel(II)-d 10 metal ion complexes Several compounds are known containing copper(II)/nickel(II) and d 10 metal ion such as Zn II , Cd II and Hg II . The types of compounds include dinuclear Cu II Zn II , Ni II Zn II , Cu II Hg II and Ni II Hg II , [25][26][27][28][29][30][31][32][33] dinuclear Cu II Cd II based polymer (linker is dicyanamide), 34 dinuclear Cu II Hg II based polymer (linker is azide), 35 trinuclear Cu II Zn II Cu II , Ni II Zn II Ni II , Cu II Cd II Cu II , Ni II Cd II Ni II and Cu II Hg II Cu II , [36][37][38][39][40][41][42] and dimer-of-dinuclear [Ni II Cd II ] 2 (linker is chloride), 44 dimer-of-dinuclear [Cu II Hg II ] 2 (Hg-C bond is linker), 32 dimer-of-dinuclear [Cu II Hg II ] 2 (linker is chloride), 45 dimer-of-trinuclear [Cu II Cd II Cu II ] 2 (linker is dca), 46 Cu II Cd II Cu II based polymer 46 etc. It has been observed that for dinuclear Cu II Zn II and Cu II Hg II , [25][26][27]31,32 trinuclear Cu II Zn II Cu II , Cu II Cd II Cu II and Cu II Hg II Cu II compounds 36,37,[39][40][41]43 in most of the cases the copper(II) centre(s) are tetracoordinated and in few cases copper(II) centre(s) are penta-coordinated with the axial position occupied by oxygen atom of bridging acetate/ formate/nitrate ligand or oxygen atom of water/N,N' dimethylformamide molecule or nitrogen atom of picoline/pyrazine/azide/dicyanamide/thiocyanate ligand, but for dinuclear Ni II Zn II , Ni II Hg II , trinuclear Ni II Zn II Ni II , and Ni II Cd II Ni II compounds 28,2...…”

“…10−13 When several second metal ions (such as s-, p-, d-, f-block metal salt) from different parts of the periodic table are treated with the Cu(II)/Ni(II) mononuclear compounds the Cu(II)/Ni(II)-second metal homo-/ hetero-nuclear complexes are produced. However various types of copper(II)/nickel(II)-second metal (s-, p-, d-, f-block metal) complexes 14−90 were reported previously from single compartmental salen-type Schiff base ligand which include dinuclear, 20,21,24,[25][26][27][28][29][30][31][32][33][47][48][49][50][80][81][82][83][84] trinucler, 22,23,[36][37][38][39][40][41][42][52][53][54][55][85][86][87] tetranuclear, 16 pentanuclear, 14 hexanuclear, 15 dimer of dinuclear, 21,32,[44][45][46]…”
