五氢化氢IRH{sub5}(PPh{sub3}){sub2}与失去H{sub2}的螯合硅烷反应，形成经典的七配位扭曲五方双锥硅多氢化合物IRH{sub3}(Disil)(PPh{sub3}){sub2}(disil：DMSB，3a；tids，3b)，得到IRH{sub4}(SIR{sub3})(PPh{sub3}){sub2}(R：Et，4a；PH，4b)与三苯基锡氢化物反应得到Ir(V)的稀有例子：IRH{sub3{-}}(SNPH{sub3}){sup 2}(PPh{sub3}){sub2}(5)。得到了3a的晶体结构。晶体数据：斜方晶系；空间群Pbca(第61号)；a=17.1534(6){Angstrom}；b=25.688(2){Angstrom}；c=19.0641(9){Angstrom}；V=8400(1){Angstrom}{sup 3}；Z=8。
The pentahydride IrH{sub 5}(PPh{sub 3}){sub 2} reacts with chelating silanes with loss of H{sub 2} to form the classical seven-coordinate distorted pentagonal bipyramidal silyl polyhydride complexes IrH{sub 3}(disil)(PPh{sub 3}){sub 2}(disil: dmsb, 3a; tids, 3b) with monodentate silanes to give IrH{sub 4}(SiR{sub 3})(PPh{sub 3}){sub 2} (R: Et, 4a; Ph, 4b) and with triphenyltin hydride to give IrH{sub 3{minus}} (SnPh{sub 3}){sup 2}(PPh{sub 3}){sub 2} (5), all rare examples of Ir(V). A crystal structure was obtained for 3a. Crystal data: orthorhombic; space group Pbca (No. 61); a = 17.1534(6) {Angstrom}; b = 25.688(2) {Angstrom}; c = 19.0641(9) {Angstrom}; V=8400(1) {Angstrom}{sup 3}; Z=8.
