“…Compound 6 shows incomplete spin crossover up to 360 K relating to the spin transition at the Fe III centres. The structures of compounds 4 and 5 are constructed from anionic sheets of [Fe III (azp) 2 ] − with cationic Fe II molecules occupying positions between the layers which are similar to other previously reported mixed-valent Fe II /Fe III complexes [17][18][19]41]. Interestingly, compound 6, which has extra MeCN molecules in the crystal lattice, shows a unique packing with a combination of all metal centres linking in the same pseudo-1D chain.…”

“…Furthermore, supramolecular assemblies in the structures of such materials can produce a cooperative effect between the spin-crossover sites [17]. To date, much of the work in this area has involved only two systems, [Fe II L x ][Fe III (dipic) 2 ] Y (L = 1,10-phenanthroline [18], 2,2 -bipyridine [19] (X = 3, Y = 2), L = terpyridine [20] (X = 2, Y = 2), and L = 2,3,5,6, tetrapyridylpyrazine [20] (X = 2, Y = 1), dipic 2− = 2,6-pyridinedicarboxylate) and a homochiral assembly of the chiral species [Fe II H 3 L][Fe III L]X 2 where H 3 L and derivatives denote a hexadentate N 6 tripod ligand containing three imidazole groups [17,[21][22][23][24].…”

Iron(III) Azadiphenolate Compounds in a New Family of Spin Crossover Iron(II)–Iron(III) Mixed-Valent Complexes

A new family of mixed valent, double salt spin crossover compounds containing anionic FeIII and cationic FeII compounds i.e., [FeII{(pz)3CH}2][FeIII(azp)2]2·2H2O (4), [FeII(TPPZ)2][FeIII(azp)2]2]·H2O (5) and [FeII(TPPZ)2][FeIII(azp)2]2]·H2O·3MeCN (6) (where (pz)3CH = tris-pyrazolylmethane, TPPZ = 2,3,5,6, tetrapyridylpyrazine and azp2− = azadiphenolato) has been synthesized and characterised. This is the first time that the rare anionic spin crossover species, [FeIII(azp)2]−, has been used as an anionic component in double salts complexes. Single crystal structures and magnetic studies showed that compound 6 exhibits a spin transition relating to one of the FeIII centres of the constituent FeII and FeIII sites. Crystal structures of the anionic and cationic precursor complexes were also analysed and compared to the double salt products thus providing a clearer picture for future crystal design in double spin crossover materials. We discuss the effects that the solvent and counterion had on the crystal packing and spin crossover properties.

Room‐Temperature Synthesis of Three Compounds Featuring the [Ge₄S₁₀]^4– Anion from a Water‐Soluble Thiogermanate Precursor

Applying a new synthetic approach in which transition metal complexes and a thiogermanate source are in different liquid phases resulted in crystallization of three new compounds with the adamantane-like [Ge 4 S 10 ] 4anion at room temperature. In the crystal structure of [Ni(cyclam)] 3 [Ni-(cyclam)(H 2 O) 2 ][Ge 4 S 10 ] 2 ·21H 2 O (I, cyclam = 1,4,8,11-tetraazacyclotetradecane), the two different Ni 2+ -centered complexes and two unique [Ge 4 S 10 ] 4anions are joined by H-bonding interactions with a water cluster composed of condensed pentameric and hexameric rings. The compound {[Mn(2,2′-bipy) 2 -(H 2 O)] 2 Ge 4 S 10 }·3H 2 O (II, bipy = bipyridine) also contains the [a] Christian-Albrechts-Universität zu Kiel,
