Title: Diversity of Chemical Bonding and Oxidation States in MS 4 Molecules of Group 8 Elements

Abstract

The geometric and electronic ground-state structures of six MS 4 molecules (M = group-8 metals Fe, Ru, Os, Hs, Sm, and Pu) have been studied by using quantum-chemical density-functional and correlated wave-function approaches. The MS 4 species are compared to analogous MO 4 species recently investi-gated (Inorg. Chem. 2016, 55: 4616). Metal oxidation state (MOS) of high value VIII appears in low- spin singlet Td geometric species (Os,Hs)S 4 and (Ru,Os,Hs)O 4, whereas low MOS=II appears in high- spin septet D 2d species Fe(S 2) 2 and (slightly excited) metastable Fe(O 2) 2. The ground states of all other molecules have intermediate MOS values, containing S 2-, S 2 2-, S2 1- (and resp. O 2--, O 1-, O 2 2-, O 2 1-) ligands, bonded by ionic, covalent and correlative contributions.

  • Does sulfur form six covalent bonds in CH{sub 3}SO{sub 2}Cl, F{sub 3}S{triple bond}N or carbon or phosphorus five bonds in F{sub 3}C=O{sup {minus}}, F{sub 3}P=O After a brief history of the viewpoints on hypervalent bonding and a comparison of analysis methods (with CH{sub 3}SO{sub 2}Cl as example), natural population and natural bond orbital analysis is applied to a series of 32-valence-electron species of X{sub 3}XY type (CF{sub 4}, F{sub 3}NO, O{sub 3}ClF, O{sub 3}PS{sup 3{minus}}, F{sub 3}SN, etc.). The {sigma}-bonding in these systems is found to be significantly ionic, and the strongly polar {sigma}*{sub AX} orbitals are found to bemore » more effective electron acceptors than the extra-valence d{sub {pi}} (A) orbitals. By generalizing our discussion to n-coordinate 8n-valence-electron species (HF{sub 2}{sup {minus}}, BF{sub 3}, ClO{sub 4}{sup {minus}}, F{sub 4}SO, F{sub 5}TeO{sup {minus}}, IF{sub 6}{sup +}, OXeF{sub 6}, etc.) and their reduced analogues that have one or more lone pairs on the central atom (SF{sub 4}, IF{sub 6}{sup {minus}}, ClF{sub 3}, etc.), we provide a classification of hypervalent (and many nonhypervalent) molecules. The simple, qualitative bonding concepts for hypervalent molecules developed here supercede the inaccurate and misleading dsp{sup 3} and d{sup 2}sp{sup 3} models that are still in widespread use.« less
  • A series of model compounds capable of intramolecular sulfur(II)-oxygen interaction of the 1,5-type was investigated by the ab initio SCF-MO method. Compounds of the type X-S-A=B-Y(Z)=O with cis configuration about A=B, containing X = F, OH, NH/sub 2/, CH/sub 3/, and SH; A = CH; B = CH and N; and Z = H, O, as well as lone pair, were studied. This results in four families containing a total of twenty compounds. The geometries of two basic planar conformations of these compounds, s-cis/s-trans (CT) and s-trans/s-trans (TT), obtained by internal rotations about the B-Y and S-C bonds, respectively, weremore » optimized by using three different basis sets. These energy minimum conformations represent optimum geometries with and without S...O interactions, respectively. Four quantities were used to measure the extent of S...O interactions. These included the lengthening of the Y-O bond on going from TT to CT (..delta..R(Y-O)), the shortening of the S...O distance (..delta..R(S...O)), the energy change between TT and CT (..delta..E(S...O)), and the Mayer type bond order in the CT conformations (B(S...O)). The linear interdependence of these four quantities indicated that each of these four parameters was about equally good measure of the extent of S...O interaction. With the aid of these numerical measures earlier qualitative principles may now be evaluated quantitatively.« less
  • The d-block transition metals are characterized by forming strong cvalent bonds involving the d orbitals in a nine-orbital spherical sp[sup 3]d[sup 5] manifold thereby leading to the familiar 18-electron rule for the stable electronic configurations of transition metal coordination and organometallic complexes. On the other hand the 4f orbitals in the lanthanides appear to participate very little in covalent bond formation so that the chemistry of the lanthanides is governed largely by electrostatic considerations similar to the chemistry of the alkali and alkaline earth metals but with a predominant +3 oxidation state. The chemistry of the actinides from at leastmore » uranium through americium exhibits some features of both the predominantly covalent bonding of the d-block transition metals and the predominantly electrostatic bonding of the lanthanides since both the 5f and 6d orbitals of the actinides can function as valence orbitals leading to an unusual 12-orbital spherical d[sup 5]f[sup 7] manifold. This paper uses elementary group theory to explore how such a d[sup 5]f[sup 7] manifold can participate in the types of covalent bonding prevalent in actinide chemistry.« less
