Triorganotin and -lead derivatives of X-benzoylglveine (BzGlyH) and N-formylglycine (ForGlyH), R3MBzGly and R3MForGly (M = Sn; R = Me, Ph. M = Pb; R = Ph) have been prepared from R3MOH and BzGlyH or ForGlyH, respectively. According to spectro­scopic data the Me3Sn groups are essentially planar; molecules of R3SnForGly are bridged by unidentate carboxylate groups and formyl-C = O groups in the solid state, while Ph3PbForGly and benzoylglycinates are bridged by bidentate carboxylate groups. NH does not coordinate to M. Pentacoordination and a polymeric nature in the solid state is also indicated by Mößbauer data of Me3SnForGly and Me3SnBzGly. In solution all compounds are monomeric.

Analysis of the weak interactions within the crystal structures of 33 complexes of various 4′-aromatic derivatives of 2,2′:6′,2″-terpyridine (tpy) shows that interactions that exceed dispersion are dominated, as expected, by cation⋯anion contacts but are associated with both ligand–ligand and ligand–solvent contacts, sometimes multicentred, in generally complicated arrays, probably largely determined by dispersion interactions between stacked aromatic units. With V(V) as the coordinating cation, there is evidence that the polarisation of the ligand results in an interaction exceeding dispersion at a carbon bound to nitrogen with oxygen or fluorine, an interaction unseen in the structures of M(II) (M = Fe, Co, Ni, Cu, Zn, Ru and Cd) complexes, except when 1,2,3-trimethoxyphenyl substituents are present in the 4′-tpy.

Complexation of the 8,8′-bis(methylsulfanyl) derivatives of cobalt and iron bis(dicarbollides) [8,8′-(MeS)2-3,3′-M(1,2-C2B9H10)2]− (M = Co, Fe) with copper, silver, palladium and rhodium leads to the formation of the corresponding chelate complexes, which is accompanied by a transition from the transoid to the cisoid conformation of the bis(dicarbollide) complex. This transition is reversible and can be used in design of coordination-driven molecular switches based on transition metal bis(dicarbollide) complexes. The solid-state structures of {(Ph3P)ClPd[8,8′- (MeS)2-3,3′-Co(1,2-C2B9H10)2-κ2-S,S′]} and {(COD)Rh[8,8′-(MeS)2-3,3′-Co(1,2-C2B9H10)2-κ2-S,S′]} were determined by single crystal X-ray diffraction.

Synthetic Saponite

A combination of solid-state NMR and 1H-NMR relaxometric investigations has been employed to characterize the structure and physico-chemical properties of a novel synthetic saponite intercalated with Gd(iii) and Y(iii) chelates.
