Triosmium carbonyl cluster complexes of bridging phosphonate, arsonate, and phosphinate ligands

The hydrogenphosphate complex of (1,5-cyclooctadiene)iridium(I), {[Bu4N][(1,5-COD)Ir·HPO4]}n: synthesis, spectroscopic characterization, and ES-MS of a new, preferred precursor to HPO42− and Bu4N+ stabilized Ir(0)n nanoclusters

“…Those papers describe interesting, crystallographically characterized H 2 OS 3 (CO) 9 (l 3 -O 3 ER) complexes (ER ¼ PR; SO; AsR) which anyone interested in the topic of PO 3 4 , SO 2À 4 , O 3 PR 2À and related organometallic complexes will wish to consult [26,27].…”

“…However, a phosphinate complex, (μ-H) 2 Os 3 -(CO) 10 (μ,η 2 -O 2 PPh 2 ), is known ( Figure 104). 236 243 This compound was prepared in the The terminal pyrazole and chloride ligands help in fulfilling the coordination requirement of the Co II ions. Other dinuclear and heterometallic Co 2 Sb 2 ensembles are summarized in Table 17.…”

“…However, a phosphinate complex, (μ-H) 2 Os 3 -(CO) 10 (μ,η 2 -O 2 PPh 2 ), is known (Figure 104). 236 12. GROUP 9 PHOSPHONATES The nuclearity of homonuclear cobalt phosphonates varies from 1 to 20, 237 while in the heterometallic systems the highest nuclearity achieved is 24.…”
