Binuclear isocyanide complexes of iridium(I)

Binuclear isocyanide complexes of iridium(I). Synthesis, structure, and hydrogen reactivity of [Ir2(m-CNR)(CNR)4(PMe2CH2PMe2)2][PF6]2 (R = 2,6-Me2C6H3, tert-C4H9). Wu, Jianxin; Reinking, Mark K.Several substances are used for example 106162-42-9 and 12112-67-3 which are their cas registry numbers.; Fanwick, Phillip E.; Kubiak, Clifford P. (Dep. Chem., Purdue Univ., West Lafayette, IN 47907, USA). Inorg. Chem., 26(2), 247-52 (English) 1987. CODEN: INOCAJ. ISSN: 0020-1669. DOCUMENT TYPE: Journal CA Section: 78 (Inorganic Chemicals and Reactions) Section cross-reference(s): 67, 75 [Ir2(m-CNR)(CNR)4(PMe2CH2PMe2)2[PF6]2 (I; R = 2,6-Me2C6H3, tert-Bu) were prepd. I (R = 2,6-Me2C6H3) crystallizes in the monoclinic space group P21/n, with a 19.388(5), b 15.193(5), c 24.060(4) ?, b 94.15(2)°, and Z = 4. The Ir-Ir sepn. of 2.7850(7) ? is consistent with a metal-metal single bond. I (R = 2,6-Me2C6H3) is fluxional in soln. Variable low-temp. 1H NMR studies of I (R = 2,6-Me2C6H3) reveal a dynamic process involving the exchange of isocyanide ligands between bridging and terminal positions. I react quant. with H2, giving [Ir2(m-H)2(CNR)4(PMe2CH2PMe2)2][PF6]2 (II). Selective 1H-decoupled 31P NMR expts. have been employed to demonstrate the dihydridic nature of II. The kinetics of the hydrogenation of I (R = 2,6-Me2C6H3) to II was studied at 0-36°. The hydrogenation of I is 1st order in [I] and zero order in [H2] (DH\ = 28 kcal mol-1; DS\ = 18 cal mol-1 K-1). .
