“…The four heterometallic complexes 14 – 16b (Table 1) belong to the MST {M 4 (μ 3 ‐X)(μ‐X) 5 } 16,23. The heterobimetallic Cu/Co complex [Cu II Co III Co II 2 Cl 3 (MeDea) 3 (CH 3 OH) 0.55 (H 2 O) 0.45 ] · (H 2 O) 0.45 ( 14 ) was initially obtained during the search for Cu/Co/Ni heterotrimetallic species with N ‐methyldiethanolamine (H 2 MeDea) as ligand 23. From the charge balance and analysis of the coordination geometries, the oxidation states of the cobalt ions were assigned as two Co II in tetrahedral and trigonal‐bipyramidal environments and Co III in an octahedral environment.…”

The synthesis of polynuclear coordination compounds, particularly heterometallic coordination compounds, remains a challenge for modern chemistry. Spontaneous self‐assembly (SSA) is a primary approach that proceeds by broad screening, typically with simple, flexible ligands and available metal salts. The “direct synthesis” is a class of SSA, but prescribes the use of zero‐valent metal(s) as a starting material, typically oxidized by air oxygen, which results in a deficiency of anions in the reaction mixture and forces deprotonation of the protic ligand(s) with the formation of unexpected products. The “direct synthesis” approach has been successfully applied to the preparation of heterometallic complexes, which has allowed the isolation of numerous complexes, many with uncommon structures. In this review we summarize our experience in the field of the “direct synthesis” of polynuclear heterometallic complexes, covering preparative and structural aspects as well as applications of the compounds obtained.

Multinuclear heterometallic oxo clusters, composed of two or more different metal cations bridged by oxo ligands, represent an important class of molecular complexes known for their unique magnetic, catalytic, and electrochemical properties resulting from cooperative interactions between the metal cations. If three or more types of metal cations can be arranged as designed, their chemical and physical properties can be precisely and flexibly controlled, potentially creating innovative materials. However, research on hetero‐trimetallic and hetero‐tetrametallic oxo clusters remains limited. This review presents an interdisciplinary search of multinuclear heterometallic oxo clusters, regardless of the type of ligand, to explain and classify their synthesis strategies and structures. By cataloging crystallographically characterized heterometallic oxo clusters using ligand‐per‐metal values and synthesis method notations, valuable insights have been gained into effective synthesis methods for the precise arrangement of metal cations. The advantages and disadvantages of one‐pot synthesis methods and synthesis strategies for achieving precise structural control of heterometallic oxo clusters are discussed with an emphasis on the prediction of their final structures. The insights from this review are expected to drive the development of synthetic and analytical techniques for the precise synthesis of heterometallic complexes in a predictable way.
