A comparative crystallochemical analysis of binary compounds and simple anhydrous salts containing pyramidal anions LO₃ (L = S, Se, Te, Cl, Br, I)

Abstract

A comparative analysis of binary compounds and 61 simple anhydrous salts M(y)(LO(3))(z) (L = S, Se, Te, Cl, Br, I) was performed using the crystallochemical program package TOPOS. A topological similarity was found between the salts and six types of binary compounds (NaCl, NiAs, PoCl(2), Tl(2)S(2), ZnTe, rutile). It is notable that these structure relationships are typical for other groups of inorganic salts: borates, carbonates, nitrates, orthophosphates, orthoarsenates, sulfates, selenates, perchlorates, molybdates and halogenides of d-metals. For all the M(y)(LO(3))(z) compounds the topology and uniformity of the ion arrays were investigated. It has been established that in 36 out of the 61 salts at least one ion array has the topology of close packing or the body-centred cubic lattice. The results obtained have allowed us to come to conclusions about the structure-forming role of the arrays of various chemical composition.

Alcohol responsive 2D coordination network of 3-(4-pyridyl)benzoate and Zinc(II)

“…The netwok topology of the compound was analysed using X-SEED, SYSTRE [17] and TOPOS [18] and checked against the Reticular Chemistry Structural Resource (RSCR) [19]. The calculated point symbol and vertex symbol were found to be 4 24 3 .…”

Rational design of two bpy-bridged 3D and 2D CoII open frameworks with similar amino-acid-based Schiff bases

“…17 As discussed above, every Co II 4 molecular square is surrounded by four μ 2 -bpy co-ligands, and each μ 2 -bpy connects two Co II 4 molecular squares in complex 1. Thus, the entire structure can be represented as a uninodal fourconnected diamond net with six-membered cyclohexane-like rings in a chair conformation if each Co II 4 molecular square and the μ 2 -bpy are defined as a four-connected node and as a linker, respectively (Fig.…”

Periodic‐Graph Approaches in Crystal Structure Prediction

“…Just after a year, O'Keeffe and coworkers [21] published the statistics for 774 valence-bonded single nets in MOFs with the same sequence of the first three leaders. In the next 4 years, the crystal structure topologies in organic, inorganic, and metal-organic compounds were systematically investigated [ [22][23][24][25][26]48]; most results of these studies are collected in the TTO databases. Thus, in valence-bonded interpenetrated inorganic and MOFs as well as in single MOFs, the leaders are dia-pcu-srs; in organic molecular crystals with hydrogen-bonded single networks, the results are similar (dia-pcu-sxd-hex) as well as for hydrogen-bonded coordination compounds (pcu-bcu-hex-dia).…”
