[(Ph 3 Sn) 3 VO 4 ]·CH 3 CN and [(Ph 3 Sn) 3 VO 4 ]·2 DMF, Triphenyltin Vanadates with Novel Chain Structures The reaction of Na 3 VO 4 with Ph 3 SnCl in a water/CH 2 Cl 2 mixture leads to the formation of [(Ph 3 Sn) 3 VO 4 ] ( 1 ). Recrystallization of 1 from toluene/CH 3 CN gives pale yellow crystals of [(Ph 3 Sn) 3 VO 4 ]·CH 3 CN ( 2 ). 2 crystallizes as coordination polymer which consists of infinite chains composed of corner‐sharing VO 4 tetrahedra and Ph 3 SnO 2 trigonal bipyramides. Additionally the VO 4 groups are connected to two terminal SnPh 3 ‐Groups containing tin atoms in a tetrahedral environment. [(Ph 3 Sn) 3 VO 4 ]·2 DMF ( 3 ) which is obtained from Na 3 VO 4 and Ph 3 SnCl in a water/DMF mixture contains a polymeric chain structure similar to 2 and additionally one of the terminal SnPh 3 groups is coordinated to a DMF solvent molecule.
