[Ph₄P][(C₅H₆N₃O₃)M(CO)₅] (M = Cr, Mo, W; C₅H₇N₃O₃ = 1,3‐Dimethyl‐cyanuric Acid). Organometallic Complexes of the 1,3‐Dimethylcyanurate Ligand

Abstract

1,3-Dimethylcyanuric acid (DMCH) forms on deprotonation and reaction with TlF its thallous salt Tl[DCM] (2) which is converted to the phosphonium salt [PPh 4 ][DCM] (3). On the reaction with M(CO) 6 , the pentacarbonylmetalate salts [Ph 4 P][(DMC)M(CO) 5 ], M ϭ Cr (4a), Mo (4b) and W (4c) are obtained. IR and NMR data of 4 reveal the DMC anion (1) to have

Syntheses, Structures, and Luminescence Properties of New Octahedral Cluster Complexes with Terminal Phenolate Ligands: [K(H2O)(CH3OH)3]2[Ph4P]2[M 6Cl12(O–C6H4–F)6] (M = Nb, Ta; Ph = phenyl)

“…The peaks of the H atoms of the phenyl rings of the [Ph 4 P] ? cation range from 7.18 to 7.81 ppm [31]. The other peaks ranging from 5.52 to 6.82 ppm are attributed to the coordinated phenolate ligands [32].…”
