Adventures in divalent early transition metal coordination chemistry: On the way to metal–metal bonded species
2017, Inorganica Chimica Acta
Citation Excerpt :
For convenience some of the ligands mentioned in the manuscript are illustrated in Scheme 1. Whenever the water molecules that contribute to the hydrogen bonding networks are removed the stability towards air significantly decreases as shown by trans-V(sacch)2(py)4, V(bipy)2(η2-SO4), [V(en)3]SO4, V(pySO3)2(py)4 [17] (Figs 7–10, respectively) as well as related amine derivatives [18–28], all of which are easily oxidized even in the solid state. However, these compounds—all of which possess V–N bonds—are thermodynamically stable and remain unchanged as long as they are protected from oxygen.
During the search for appropriate early-transition-element starting materials to generate dinuclear paddlewheel species having metal–metal bonded cores of the type M₂⁴⁺, it was necessary to gain more insight into the relatively unexplored coordination chemistries of divalent vanadium, niobium and titanium. Here it is shown how an increased understanding of the chemical behavior eventually led to such species for vanadium and niobium while those of titanium remain elusive. The narrative chronicles some of the strategies behind the preparations and also how careful data analyses provided the blueprint for fully-designed syntheses. Even though the emphasis is on the syntheses, the figures show the structures of the compounds synthesized and structurally characterized in our laboratory in conjunction with Al Cotton.

Trinuclear complexes of four-coordinate iron and cobalt: Some reflections on the importance of the reaction conditions for the formation of metal-metal bonds
1998, Polyhedron
The mononuclear, tetrahedral iron and cobalt complexes, FeCl₂(Hhpp)₂, I, and CoCl₂(Hhpp)₂, II, are readily formed by the reaction of the metal (II) chloride with Hhpp. Compound II crystallized as blue blocks in the space group Fdd2. The reaction of I with LiMe yielded the trinuclear complex Fe₃Cl₂(hpp)₄, III, which crystallized as colorless blocks in the space group P2₁/n. A cobalt complex Co₃Cl₂(hpp)₄, IV, analogous to III, was synthesized by the reaction of CoCl₂ with Lihpp. Compound IV crystallized as blue blocks in the space group P2₁. Both III and IV have three four-coordinate metal centers and contain no metal–metal bonds, two metal atoms are each bound to one chlorine and three nitrogen atoms while the third one is bound to four nitrogen atoms.

The coordination chemistry of the amidine ligand
1994, Coordination Chemistry Reviews
Amidines, R'NH—C(R)NR', as for the isoelectronic carboxylic acids, form a large number of transition metal derivatives, the metals varying from early metals in high oxidation states to the later metals in lower oxidation states. Various bonding modes for the amidino group are involved, and are reviewed with reference to other aza-allyl systems. Much current interest arises from the ability of the ligand to bridge between metals, facilitating metal-metal bonding, and from the use of unsymmetrically substituted amidino groups to produce chiral complexes. Methods of synthesis are reviewed, together with infrared and NMR spectroscopic, mass spectrometric and thermal analysis data. The complexes are introduced systematically according to their Period Group, making easy access to information on specific metal complexes. Mixed-metal complexes containing amidino groups bridging between different metals are considered separately. X-ray crystallographic data is collated in a table, thus providing an accessible source for reference purposes. Source material for the review amounts to about 300 references.
