Abstract
- The reaction of the arylphosphonic acid esters 4,4′-[( i-PrO)<subscript>2</subscript>P(O)]C<subscript>6</subscript>H<subscript>4</subscript>C<subscript>6</subscript>H<subscript>4</subscript>[P(O)(O i-Pr)<subscript>2</subscript>] ( L<superscript>1</superscript>), 1,3,5-[( i-PrO)<subscript>2</subscript>P(O)]<subscript>3</subscript>C<subscript>6</subscript>H<subscript>3</subscript> ( L<superscript>2</superscript>), and 5- t-Bu-1,3-[( i-PrO)<subscript>2</subscript>P(O)]<subscript>2</subscript>C<subscript>6</subscript>H<subscript>3</subscript> ( L<superscript>3</superscript>), respectively, with bismuth halides BiX<subscript>3</subscript> (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 [(BiCl<subscript>3</subscript>)( L<superscript>1</superscript>)] ( 1), [(BiBr<subscript>3</subscript>)( L<superscript>1</superscript>)]·0.25CH<subscript>3</subscript>CN ( 2·0.25CH<subscript>3</subscript>CN), [(BiI<subscript>3</subscript>)<subscript>2</subscript>( L<superscript>1</superscript>)]·0.25CH<subscript>3</subscript>CN ( 3·0.25CH<subscript>3</subscript>CN), [(BiCl<subscript>3</subscript>)( L<superscript>2</superscript>)] ( 4), [(BiCl<subscript>3</subscript>)<subscript>2</subscript>( L<superscript>2</superscript>)] ( 5), [(BiBr<subscript>3</subscript>)<subscript>2</subscript> ( L<superscript>2</superscript>)]·CH<subscript>3</subscript>CN ( 6·CH<subscript>3</subscript>CN), and [(BiCl<subscript>3</subscript>)( L<superscript>3</superscript>)] ( 7) are presented. Thermal analysis of [(BiCl<subscript>3</subscript>)<subscript>2</subscript>( L<superscript>2</superscript>)] ( 5) is indicative of a conversion of the complexes into a bismuth phosphonate by complete i-PrX elimination, whereas for [(BiBr<subscript>3</subscript>)<subscript>2</subscript>( L<superscript>2</superscript>)] ( 6), elimination of i-PrBr and BiBr<subscript>3</subscript> is assumed. Compounds 1- 3 form one-dimensional coordination polymers, whereas two-dimensional networks are observed for compounds 4- 7. [ABSTRACT FROM AUTHOR]
