“…It has a spin quantum number of 1/2 and a wide chemical shift range of about 400 ppm. This nucleus is a very convenient NMR probe for studying molecular complexes [99,[204][205][206], organometallics [207][208][209][210], and mobility at interfaces [211][212][213]. For example, 31 P NMR has been used to study the effect of temperature and hydration on the mobility of small to bulky molecules loaded onto mesoporous silica [214].…”

This review discusses molecular adducts, whose composition allows a symmetric structure. Such adducts are popular model systems, as they are useful for analyzing the effect of structure on the property selected for study since they allow one to reduce the number of parameters. The main objectives of this discussion are to evaluate the influence of the surroundings on the symmetry of these adducts, steric hindrances within the adducts, competition between different noncovalent interactions responsible for stabilizing the adducts, and experimental methods that can be used to study the symmetry at different time scales. This review considers the following central binding units: hydrogen (proton), halogen (anion), metal (cation), water (hydrogen peroxide).

“…The 31 P isotope is present in 100% natural abundance, has a spin quantum number of 1/2 and a chemical shift range of more than 400 ppm. 31 P NMR can be routinely used in the evaluation of the structure of organic complexes in solution [90,91] and solids [92][93][94] including organometallic compounds [26,[95][96][97][98]. Molecules containing phosphorus are very convenient NMR probes for studying mobility at interfaces [99][100][101].…”

There are varieties of methods available for the exploration of solids using nuclear magnetic resonance (NMR) spectroscopy. Some of these methods are quite sophisticated, others require specialized equipment. This review is addressed to those for whom NMR is not the main research method. It discusses simple methods that can be applied to solids with little or no adaptation to a specific system. Despite their technical simplicity and ease of use, these methods are powerful analytical tools that provide unique insights into the structure, dynamics, and noncovalent interactions in homo- and heterogeneous systems. Particular attention is paid to the characterization of porous materials and solids containing phosphorus. 31P NMR of organometallic compounds has been used as an example of how theoretical calculations can help in deeper analysis of experimental data.

“…The tetrahedrane complexes [{CpMo(CO) 2 } 2 (μ,η 2:2 -EE′)] [E = E′ = P ( A ); E = P, E′ = As ( B ); E = P, E′ = Sb ( C ); E = E′ = As ( D ); E = As, E′ = Sb ( E ); E = E′ = Sb ( F )], which are isolobal to the E 4 (E = P, As) tetrahedranes, are among the simplest in the series of E n ligand complexes, as their coordination behavior is more predictable due to only two E-donor atoms. Hence, our group studied the coordination chemistry of the homoleptic congeners [{CpMo(CO) 2 } 2 (μ,η 2:2 -P 2 )] ( A ), ,, [{CpMo(CO) 2 } 2 (μ,η 2:2 -As 2 )] ( D ) , and [{CpMo(CO) 2 } 2 (μ,η 2:2 -Sb 2 )] ( F ) , in detail during the last years. Regarding the more elaborate heterodiatomic complexes [{CpMo(CO) 2 } 2 (μ,η 2:2 -PE)] (E = As ( B ), Sb ( C )), only few reports on their coordination toward CuX (X = Cl, Br, I), (dppf)Cu (dppf = 1,1′-bis(diphenylphosphino)-ferrocene) and M[TEF] (M = Ag, Cu) as well as on their oxidation chemistry , are known.…”

The coordination chemistry of the homo-and heterodipnictogen tetrahedrane complexes [{CpMo-(CO) 2 } 2 (μ,η 2:2 -EE′)] (E, E′ = P, As, Sb) (A−F) toward Tl[BArF 24 ] ([BArF 24 ] − = [B(3,5-C 6 H 3 (CF 3 ) 2 ) 4 ] − ) was studied. Controlled by the used tetrahedranes A−F, and thus depending on the respective pnictogen atoms, the monomers [Tl(η 2 -A)][BArF 24 ] ([A]Tl) and [Tl(η 2 -B)][BArF 24 ] ([B]Tl), the double substituted6 Tl 2 ) were obtained. Utilization of [BArF 24 ] − promises additional stabilization of Tl I via η 6coordination of two of its aryl rings as found in compounds [A] Tl, [B]Tl and [C] 2 Tl. Within the series of reactivity of A−F, the heavier congeners D, E and F tend to form larger aggregates in which σ(E−E′) bond contributions to the coordination behavior were observed. Interatomic distances suggest the presence of Tl••• Tl interactions in [E] 5 Tl 2 and [F] 6 Tl 2 . The features of the respective coordination compounds were studied in the solid-state as well as in solution. For the latter at least a partial dissociation of the assemblies in solution was indicated. The isolated solid-state aggregates are the first examples of heterodipnictogen units as ligands in self-assembled Tl I -based coordination compounds.
