Borophosphates (intermediate compounds of the system MxOy−B2O3−P2O5−(H2O)) contain complex anionic structures built of BO4, BO3, and PO4 groups and their partially protonated species, respectively. A first approach to the development of a structural chemistry of borophosphates is based on linking principles of the primary building units following the general line of silicate crystal chemistry. The crystal structures of borophosphates are first divided into anhydrous and hydrated phases. Further gradings are based on the (molar) B:P ratios. The structural chemistry of borophosphate anions already extends from isolated species, oligomers, rings, and chains to layers and frameworks. Additional characteristics are integration of planar BO3 groups, preferred formation of 3-membered rings, and unusual branching of tetrahedral chains. P−O−P linking in borophosphates is not observed up to now.

Incorporating different anions with varied ionic sizes and charges is a rapidly growing approach to bring out unusual physical properties among various classes of solid-state materials, pnictides and chalcogenides in particular. This minireview is focused on hetero-anionic materials based on the pnictogens, which have been demonstrated to offer an impressive diversity of crystal chemistry and electronic structures. In addition, many pnictide oxides or oxypnictides, over the course of the last decade, have been shown to exhibit a broad spectrum of superconducting, magnetic, and semiconducting properties. However, the structural diversity of the mixed-anion materials is far greater than the several known structure types, or their variants, of the well-known layered superconductive materials. Therefore, with this treatise, we aim to provide a comprehensive overview of the crystal chemistry of pnictide oxides by recounting almost 40 different structures of such ternary and multinary compounds. In addition to the structural aspects, we also highlight some of the challenges associated with the synthesis, and briefly summarize reported, to date, physical properties of this remarkable class of solids.

Abstract The solid‐state chemistry of phosphides, phosphide oxides, and phosphide halides is reviewed. Phosphorus is outstanding, since no other element approaches phosphorus in the variety of homoatomic connected polyanions formed, as a result of its relatively low electronegativity and stereochemical features. The article covers the various synthesis techniques for solid‐state phosphides, the crystal chemistry, and chemical bonding. Besides the metal‐rich phosphides with pronounced metal–metal bonding, the large family of polyphosphides, which exhibits an unexpected wealth of chemical composition, is discussed. Furthermore, the largely varying magnetic, electronic, and catalytic properties are reviewed.

Abstract Some aspects of the evolution of structural chemistry are described from the personal perspective of a student of Jack Dunitz who started working for a Ph.D. in crystal chemistry in the mid‐1960s. The importance and the change of emphasis of X‐ray crystal structure determination through the decades is sketched and related to technological advances. Activities beyond standard structure determination by single‐crystal and powder diffraction, some of them significantly underdeveloped, are indicated. While crystal structure determination has become an important, if not indispensable, analytical tool supporting the widespread objectives of the synthetic chemists, structural chemistry has also developed a deep physical understanding of the concept of structure at the atomic length scale and enabled the organization of an enormous volume of individual observations based on the notions of chemical bonding.
