“…In comparison with amidines, guanidines, β‐diimines, and aminotroponimines, amidoamines offer some advantages . Their saturated backbone suppresses the delocalization and inhibits a non‐innocent behavior, which is of particular importance as in dinuclear complexes ligand‐centered reactions are regularly observed.…”

Polytopic ligands have become ubiquitous in coordination chemistry because they grant access to a variety of mono‐ and polynuclear complexes of transition metals as well as rare‐earth and main‐group elements. Nitrogen‐based ditopic ligands, in which two monoanionic N,N‐binding sites are framed within one molecule, are of particular importance and are therefore the primary focus of this review. In detail, bis(amidine)s, bis(guanidine)s, bis(β‐diimine)s, bis(aminotroponimine)s, bis(pyrrolimine)s, and miscellaneous bis(N,N‐chelating) ligands are reviewed. In addition to the general synthetic protocols, the application of these ligands is discussed along with their coordination chemistry, the multifarious binding modes, and the ability of these ligands to bridge two (or more) metal(loids).

A facile and efficient one‐pot strategy for the preparation of 1,2,3‐tri‐ and 1,1,2,3‐tetrasubstituted bis(guanidine)s by starting from from readily available bis(thiourea)s has been successfully developed. The reaction provides products that contain a range of terminal and bridging groups. After a simple workup procedure, the products were obtained in analytically pure and in good to excellent yields.

Pyridin-2-ylmethyl-tert-butylamine dimethyl aluminum complex with a planar five-membered ring was synthesized and characterized by elemental analysis, UV-Vis spectra, TG/DSC, 1 H NMR, and 13 C NMR. Through single-crystal diffraction, it is proved that the structure of the alkyl aluminum complex is a planar five-membered ring. By comparison the crystal data of 11 kinds of five-membered ring dialkyl aluminum complexes, we found that the planar five-membered ring dialkyl aluminum is formed when there is at least one unequal sp 2 hybrid nitrogen in the ligand. TG/DSC study of the compound's thermodynamic properties showed the thermal decomposition temperature of complex 7 was determined to be 210°C. The rigid plane structure of the product was proved by fluorescence analysis. When the excitation wavelength was 380 nm, the emission wavelength was 478 nm.
