Lignin was isolated from wet Banana pseudostem with 2% NaOH solution by boiling. The isolated lignin was treated with urea and called uro-lignin. IR, Mass and NMR spectra of urolignin were taken to determine its molecular structure. DOI: 10.3329/jbas.v33i2.4106 Journal of Bangladesh Academy of Sciences, Vol. 33, No. 2, 227-229, 2009

The solid-state molecular structure determination of the bimetallic osmium-tin compound [(?-H)Os2(CO)4(SnPh3)2(?-HSnPh2)(?-dppf)] (1) was carried out to determine the relative orientationof the coordinated ligands. Compound 1 crystallizes in the monoclinic space group P 21/c with a =22.366(7), b = 14.217(4), c = 25.213(8) Å, ? = 98.865(7)°, Z = 8 and V = 7921(4) Å3. It is a 34-electron bimetallic cluster with the Os-Os edge concomitantly bridged by a dppf and two HSnPh2 ligands DOI: http://dx.doi.org/10.3329/jbas.v38i1.20218 Journal of Bangladesh Academy of Sciences, Vol. 38, No. 1, 97-101, 2014

The species R−C7H7Mo(CO)3 (R=−CH2COCH3,−CH(CH3)COCH3,−CH(CH)(CH3)2COCH3) have been synthesized by electrolysing [η7-C7H7Mo(CO)3]+, η7-C7H7Mo(CO)2Br and the dimers [C7H7Mo(CO)3]2 and (C7H7)2Mo(CO)3, respectively, in suitable ketones and HBr. 1H NMR spectra and the X-ray structure determination of (CH3−CO−CH(CH3)−C7H7)Mo(CO)3 revealed the CH3−CO−CH(CH3)-group being bonded to the cycloheptatriene ligand via the α-carbon atom of the ethyl group.
