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.
