摘要：
Complexes [Bi(phen)(2)(NO3)(NCS)(2)(MeOH)] and [Bi(phen)(2)(NO3)(2)(NCS)] have been synthesized and characterized by their IR. spectra and elemental analyses. The structure of the [Bi(phen)(2)(NO3)(NCS)(2)(MeOH)] complex has been confirmed by X-ray crystallography. The Bi atoms are unsymmetrically eight-coordinated, N6O2. The arrangement of the ligands does not show a gap in the coordination geometry around the Bi(III) ion, indicating that its lone pair of electrons is not active. The thiocyanate ligands are coordinated to the bismuth atom via the nitrogen atom. There is pi-pi stacking interactions between the parallel aromatic rings belonging to adjacent chains.
