“…The normal Sn--O bond length falls in the range 1.9-2.1 A even in penta-and hexacoordination (for a review, see Ho & Zuckerman, 1973 The 0(4) atom of each perchlorate has a very short hydrogen-bonded distance to the hydroxyl H(19) atom of an adjacent dimer, 2.06 (9)/~. This interaction gives rise to an array of continuous chains (Fig.…”

“…This compound has been described as a substrate of peptide syntheses as well [14]. Amino acids and dipeptides which are considered potentially polydentate ligands could afford interesting structural possibilities when coordinated to organotin(IV) groups, since organotin(IV) compounds adopt higher coordination numbers whenever favorable conditions exist [15]. …”

Five novel tin Schiff base complexes with histidine analogues (derived from the condensation reaction between L-histidine and 3,5-di-tert-butyl-2-hydroxybenzaldehyde) have been synthesized and characterized. Characterization has been completed by IR and high-resolution mass spectroscopy, 1D and 2D solution NMR (1H, 13C and 119Sn), as well as solid state 119Sn NMR. The spectroscopic evidence shows two types of structures: a trigonal bipyramidal stereochemistry with the tin atom coordinated to five donating atoms (two oxygen atoms, one nitrogen atom, and two carbon atoms belonging to the alkyl moieties), where one molecule of ligand is coordinated in a three dentate fashion. The second structure is spectroscopically described as a tetrahedral tin complex with four donating atoms (one oxygen atom coordinated to the metal and three carbon atoms belonging to the alkyl or aryl substituents), with one molecule of ligand attached. The antimicrobial activity of the tin compounds has been tested against the growth of bacteria in vitro to assess their bactericidal properties. While pentacoordinated compounds 1, 2, and 3 are described as moderate effective to noneffective drugs against both Gram-positive and Gram-negative bacteria, tetracoordinated tin(IV) compounds 4 and 5 are considered as moderate effective and most effective compounds, respectively, against the methicillin-resistant Staphylococcus aureus strains (Gram-positive).

“…M−E σ-bonding effects have also been investigated and were shown to be particularly significant for heavier elements (E), e.g. in transition metal stannyl complexes . We shall attempt to shed more light on the (presently) large and somewhat confusing array of theoretical, structural, and thermodynamic data related to transition metal−silicon bonds.…”

The (trichlorosilyl) (and -germyl)metal carbonyls Co(CO) 4 SiCl 3 , Co(CO) 4 GeCl 3 , Mn(CO) 5 -SiCl 3 , and cis-Fe(CO) 4 (SiCl 3 ) 2 have been synthesized in high yields. He I photoelectron spectra (UPS) of the complexes have been measured and interpreted on the basis of empirical arguments and density functional theory (DFT) calculations. For cis/trans-Fe(CO) 4 (SiCl 3 ) 2 isomers the calculations predict the trans-isomer to be more stable than cis by 15.2 kJ mol -1 . The cis-isomer is exclusively present in the solid state and in the gas phase. UPS results suggest the importance of charge polarization effects and the lack of π-back-donation along TM-Si bonds. The calculated M-Si bond distances amounted to 2.34 Å (Co-Si), 2.43 Å (Co-Ge), 2.47 Å (Mn-Si), 2.41 Å (trans-Fe-Si), and 2.45 Å (cis-Fe-Si). For Co(CO) 4 SiCl 3 , the DFT calculated Co-Si bond dissociation energy was 317.7 kJ mol -1 , compared to 222.2 kJ mol -1 for Co-C energy in Co(CO) 4 CCl 3 .
