The reaction of the arylphosphonic acid esters 4,4′-[( i-PrO)2P(O)]C6H4C6H4[P(O)(O i-Pr)2] ( L1), 1,3,5-[( i-PrO)2P(O)]3C6H3 ( L2), and 5- t-Bu-1,3-[( i-PrO)2P(O)]2C6H3 ( L3), 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)( L1)] ( 1), [(BiBr3)( L1)]·0.25CH3CN ( 2·0.25CH3CN), [(BiI3)2( L1)]·0.25CH3CN ( 3·0.25CH3CN), [(BiCl3)( L2)] ( 4), [(BiCl3)2( L2)] ( 5), [(BiBr3)2 ( L2)]·CH3CN ( 6·CH3CN), and [(BiCl3)( L3)] ( 7) are presented. Thermal analysis of [(BiCl3)2( L2)] ( 5) is indicative of a conversion of the complexes into a bismuth phosphonate by complete i-PrX elimination, whereas for [(BiBr3)2( L2)] ( 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. [ABSTRACT FROM AUTHOR]

The crystal structure of the title compound shows the [K(18-crown-6)]+ cation and [{2,6-(Me2NCH2)2C6H3}SnF4]- anion, which are held together through two potassium-fluorine and one potassium-tin electrostatic interaction. The tin atom is hexacoordinated by one carbon and four fluorine atoms, and an intramolecular N→Sn interaction. It has a distorted octahedral configuration. Electrostatic interactions between two fluorine atoms and hydrogen atoms from two different cation-anion pairs generate a double-chain polymeric supramolecular structure, containing both isomers.
