The crystal structure of tetraphenylphosphonium trichloro-(cis-but-2-en-1,4-diol)platinum(II)

The crystal structure of trans-dichloro(dimethyl sulphoxide)(2-picoline)platinum(II)

“…1 O-S-C(2) 106.1 (7) C(I)-S-C(2) 99.6 (7) Pt-N-C (3) 116.0 (8) Pt-N-C (7) 125.7 (8) 2.296 A) (Melanson, Hubert & Rochon, 1976), in cis-[Pt(DMSO)(2-picoline)C12] (2.288 /~) (Melanson & Rochon, 1977) and in trans-[Pt(diisopropyl sulphoxide)(l-methylcytosine)C12] (2.304 and 2.287 /~) (Lock, Speranzini & Powell, 1976 (Jarvis, Kilbourn & Owston, 1971;Beauchamp, Rochon & Theophanides, 1973;Colapietro & Zambonelli, 1971;Spagna & ZamboneUi, 1973). The Pt-N distance of 2.046/~, is of about the expected value, and agrees well with the value of 2.062/~ found for the corresponding cis isomer and the value of 2.058 A found by Lock, Speranzini & Powell (1976).…”

Comparison of .sigma.-alkyl and .sigma.-perfluoroalkyl groups as ligands. 2. Crystal and molecular structures of dimethyl[(2-vinylphenyl)diphenylphosphine]platinum(II) and bis(trifluoromethyl)[(2-vinylphenyl)diphenylphosphine]platinum(II)

“…NMR (CDC13, 6): 7.48, 7.9 (br, mult, aromatic ), 6.50 (dd of 195Pt 1:4:1 triplets, fífl, 5.50 (d of 195Pt 1:4:1 triplets, H2), 4.00 (dd of 19SPt 1:4:1 triplets, H3) (Hi, H2, and H3 are defined in Figure 1); JHl_H2 = 8 Hz, /HrH3 = 14 Hz, /h2-h3 < 1 Hz, /p-H,, Jp-h2 < 1 Hz, 7p-h3 = 4 Hz, / -| = 16 Hz, /Pi_h2 = 26 Hz. The 195Pt satellites of H3 were obscured by signals arising from small amounts of impurity and by the high noise level necessitated by the low solubility of 2 in CDC13, but 7 ,_ 3 is probably ca.…”

Stereochemistry of Platinum Organometallics

“…In twelve derivatives both isomeric classes belong to the homo-monoclinic [11,[21][22][23][24][25][26][27][28], orthorhombic [18], triclinic [19,20] and tetragonal [35,36]. The remaining examples differ from each other not only by degree of distortion but also by crystal class.…”
