This review highlights the use and great potential of liquid metals as exotic and powerful solvents (i.e. fluxes) for the synthesis of intermetallic phases. The results presented demonstrate that considerable advances in the discovery of novel and complex phases are achievable utilizing molten metals as solvents. A wide cross-section of examples of flux-grown intermetallic phases and related solids are discussed and a brief history of the origins of flux chemistry is given. The most commonly used metal fluxes are surveyed and where possible, the underlying principal reasons that make the flux reaction work are discussed.

Ziel dieses Aufsatzes ist es, die Vorzüge von flüssigen Metallen als Lösungsmittel bei der Synthese intermetallischer und ähnlich zusammengesetzter Verbindungen aufzuzeigen. Eine Vielzahl neuer Phasen mit zum Teil ungewöhnlichen Zusammensetzungen wurde in den letzten Jahren auf diese Weise erstmals hergestellt. Nach einem kurzen historischen Überblick werden die vorteilhaften Eigenschaften der eingesetzten Metallschmelzen (Flussmittel, Flux) für die Synthese eines breiten Spektrums von Verbindungen besprochen.

“…Mixed‐valent Ni 0,I is observed in Ba 2 (Ba 6 N)[NiN] 6 8 and Li 3 Sr 3 Ni 4 N 4 9 as well as in Ba 2 [(Li 1− x Ni x )Ni 2 N 2 ],10 a solid solution variant of the title compound Ba 2 [Ni 3 N 2 ] with “Ba 2 [LiNi 2 N 2 ]”, but no physical property investigations on any of the mixed‐valent compounds have been reported up to now. Higher oxidation states (up to Ni II ) were reported in Li 5 [NiN 3 ],11, 12 Li[NiN],12 and Sr 2 [NiN 2 ],13 but at least the latter compound remains doubtful 14…”

The ternary alkaline-earth nitridonickelate Ba2[Ni3N2] (Ba2[NiI2Ni0N2]) was prepared by the reaction of mixtures of Ba2N and Ni in nitrogen gas of ambient back-pressure at 1173 K. The crystal structure determined by X-ray single-crystal and powder diffraction methods as well as from neutron diffraction data at various temperatures between 2 and 298 K is orthorhombic (Cmca (no. 64), 298 K: a=715.27(18) pm, b=1032.99(21) pm, c=740.12(20) pm) and provides the first example of a nitridonickelate with a two-dimensional complex anion. The Ni2 atom is described with a split position and the corresponding superstructure variants are investigated by theoretical full-potential nonorthogonal local-orbital calculations (FPLO). The average oxidation state of Ni in Ba2[Ni3N2] is +0.67, the lowest average value observed in nitridonickelates so far. Investigations of the physical properties demonstrate that Ba2[Ni3N2] acts as a "poor" metal with a large resistivity of approximately 2.7 mOmega cm at 300 K and exhibits low-dimensional magnetism with antiferromagnetic ordering at T approximately 90 K. XAS spectra correspond with low-valent Ni states.
