D-Lactobionic acid (4-O-β-D-galactopyranosyl-D-gluconic acid) complexes of Cs(I) ion and di-n-butyltin(IV)2+ were prepared in the solid state. The bonding sites of the ligands were verified by means of FTIR, Raman and 13C-NMR spectroscopic measurements. The Cs-D-lactobionate was obtained in single-crystal form. The X-ray crystallographic results on Cs-D-lactobionate demonstrated that each Cs(I) ion is bonded to four D-lactobionate ions, forming an intricate 3D network. The asymmetric unit consists of one Cs(I), one D-lactobionate ion and one water molecule. For the di-n-butyltin(IV) complex, Mössbauer PQS calculations indicated octahedral and trigonal-bipyramidal stereochemistry around the central tin atom in the oligomeric compound. In DMSO solution the polymeric structure do not remain as shown by 13C-NMR measurement.
