The reaction of the arylphosphonic acid esters 4,4%26apos;-[(i-PrO)(2)P(O)]C6H4C6H4[P(O)(Oi-Pr)(2)] (L-1), 1,3,5-[(i-PrO)(2)P(O)](3)C6H3 (L-2), and 5-t-Bu-1,3-[(i-PrO)(2)P(O)](2)C6H3 (L-3), respectively, with bismuth halides BiX3 (X = Cl, Br, I) gave seven novel bismuth coordination polymers that have been characterized by single-crystal X-ray diffraction analysis. The solid-state structures of [(BiCl3)(L-1)] (1), [(BiBr3)(L-1)]center dot 0.25CH(3)CN (2 center dot 0.25CH(3)CN), [(BiI3)(2)(L-1)]center dot 0.25CH(3)CN (3 center dot 0.25CH(3)CN), [(BiCl3)(L-2)] (4), [(BiCl3)(2)(L-2)] (5), [(BiBr3)(2) (L-2)]center dot CH3CN (6 center dot CH3CN), and [(BiCl3)(L-3)] (7) are presented. Thermal analysis of [(BiCl3)(2)(L-2)] (5) is indicative of a conversion of the complexes into a bismuth phosphonate by complete i-PrX elimination, whereas for [(BiBr3)(2)(L-2)] (6), elimination of i-PrBr and BiBr3 is assumed. Compounds 1-3 form one-dimensional coordination polymers, whereas two-dimensional networks are observed for compounds 4-7.
