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.

Lanthanoid-nickel-phosphides with ThCr2Si2-type structure

Die Verbindungen Y2Ni12P7 und Ln2Ni12P7 (Ln = Ce, Pr, Nd, Sm, Eu, Tb, Dy, Ho, Er, Tm, Ln) werden erstmals hergestellt und durch ihre Gitterkonstanten charakterisiert. Ihre Kristallstruktur entspricht der von Zr2Fe12P7. Die Strukturen von Er2Co12P7 und Er2Ni12P7 werden aus Einkristall-Diffraktometerdaten verfeinert. Die chemische Bindung und die Frage der richtigen Raumpruppe fur diese und die ahnlich kristallisierenden Verbindungen V12P7 und Cr12P7 werden diskutiert.

The compounds Y2Ni12P7 and Ln2Ni12P7 (Ln = Ce, Pr, Nd, Sm, Eu, Tb, Dy, Ho, Er, Tm, Lu) were prepared for the first time and characterized by their lattice constants. Their crystal structure corresponds to that of Zr2Fe12P7. The structure of Er2Co12O7 and Er2Ni12P7 were refined from single-crystal counter data. Chemical bonding and the question of the proper space group for those and the closely related compounds V12P7 and Cr12P7 are discussed.
