Twelve new organotin(IV) complexes of the type RnSnLm [where n = 3, m = 1, R = CH(3) or C(6)H(5); n = 2, m = 2, R = C(6)H(5) or C(4)H(9) ; L = anion of Schiff bases derived from the condensation of 2-amino-5-(o-anisyl)-l,3,4-thiadiazole with salicylaldehyde (HL-1), 2- hydroxynaphthaldehyde (HL-2) and 2-hydroxyacetophenone (HL-3)] have been synthesized and characterized by elemental analysis, mo...

Four new organotin(IV) complexes of the type [MeSnCl(dact)] (2), [BuSnCl(dact)] (3), [PhSnCl(dact)] (4) and [Ph2Sn(dact)] (5) were synthesized by the direct reaction of 2-hydroxyacetophenone-N(4)cyclohexylthiosemicarbazone [H2dact, (1)] and organotin(IV) chloride(s) in absolute methanol. The ligand [H2dact, (1)] and its organotin(IV) complexes (2–5) have been characterized by CHN analyses, mola...

Polydimethylsiloxane (PDMS) is widely used as a cell culture platform to produce micro- and nano-technology based microdevices. However, the native PDMS surface is not suitable for cell adhesion and is always subject to bacterial pollution and cancer cell invasion. Coating the PDMS surface with antibacterial or anticancer materials often causes considerable harm to the non-cancer mammalian cell...

Z. Naturforsch. 55 b, 1037-1044 (2000); received July 28, 2000 Nonadentate Ligand, Schiff Base, Nickel The tetrapodal pentaamine 2,6-C5H3N[CMe(CH2NH2)2l2 (pyN_u 1) readily reacts with four equivalents of 2-hydroxyphenyl-substituted carbonyl compounds, such as (i) 2-hydroxybenzaldehyde, (ii) 2,4-dihydroxybenzaldehyde, (iii) 3,5-di-rm-butyl-2-hydroxybenzaldehyde, and (iv) 2-hydroxyacetophenone, t...

A novel complex of cadmium (II) [CdL0.5(NO3)(H2O)](1), L= N,N-bis (O-hydroxyacetophenone) ethylene diamine, have been synthesized as single crystal and nano size. Compound 1 in nano size was obtained under sonochemical irradiation and has been characterized by IR, 1HNMR spectroscopy, X-ray powder diffraction (XRD) and scanni...
