| Abstract: | The first triorganotin(IV) pentacyanopropenides, R3Sn(H2O)2]C3(CN)5] (R = Me ( 2 ), nBu ( 3 ), Ph ( 4 ) were prepared by treatment of AgC3(CN)5] ( 1 ) with equimolar amounts of R3SnCl in reagent grade THF. In a similar manner, dark red R3Sn(H2O)2]N{C(CN)C(CN)2}2] ( 6 ) containing the hexacyanoazapentadienyl anion was prepared in 55 % yield. The molecular structure of Ph3Sn(H2O)2]C3(CN)5] ( 4 ) was determined by X‐ray diffraction. The crystal structure consists of separated trigonal‐bipyramidal Ph3Sn(H2O)2]+ cations and nearly planar C3(CN)5]– anions which are linked through O–H ··· N hydrogen bonds to give a three‐dimensional network. |
