The syntheses and reactivity studies of silsesquioxane-borato complexes are described. Treatment of B(C6F5)(3) with (c- C5H9)(7)Si8O12(OH) and (c-C5H9)(7)Si7O9(OH)(3) in the presence of a Bronsted base yields the silsesquioxane-borates X+{[(C- C5H9)(7)Si8O13]B(C6F5)3}(-) (1a, X+ = PhN(H)Me-2(+); 1b, X+ = Et3NH+) and X+{[(c-C5H9)(7)Si-7(OH)(2)O-10]B ...

Tris(pyrazolyl)borato-ruthenium carbonyl complexes
Journal of Organometallic Chemistry, 1971Abstract The reaction between Ru 3 (CO) 12 and potassium tris(pyrazoly)borate, KHBpz 3 , gives a deep red solution from which the compounds HBpz 3 Ru(CO) 2 X [X = Cl, Br, I] may be obtained on treatment with the appropriate halogen. The chemistry of some related compounds containing ruthenium or iron is briefly discussed.

Bis[hydrotris(1-pyrazolyl-N2)borato]zinc(II)
Acta Crystallographica Section C Crystal Structure Communications, 1995The crystal structure of the title compound, [Zn(C 9 H 10 -BN 6 ) 2 ], has been determined. The Zn II ion is coordinated by six N atoms, one from each of the six pyrazole rings. The coordination geometry about the Zn II ion is distorted octahedral.

Photochemistry of Dihydrido(hydrotris(3,5-dimethylpyrazolyl)borato)(Z-cyclooctene)iridium. Synthetic Intermediates and Mechanism of the Photochemical Formation of Hydridophenyl(hydrotris(3,5-dimethylpyrazolyl)borato)(trimethyl phosphite)iridium [PDF]
Inorganic Chemistry, 1996 The photolysis of a benzene solution of [Tp(Me2)IrH(2)(COE)], 1 (Tp(Me2) = hydrotris(3,5-dimethylpyrazolyl)borate, COE = Z-cyclooctene), in the presence of P(OMe)(3), gives the stable novel complex [Tp(Me2)IrH(C(6)H(5))(P(OMe)(3))], 3a. The photochemical syntheses of [Tp(Me2)IrH(2)(P(OMe)(3))], from 1 and P(OMe)(3) in diethyl ether, and [Tp(Me2)IrH(2 ...

Borato-1,2-diaminocyclohexane Platinum (II), a Novel Anti-Tumor Drug
Biochemical and Biophysical Research Communications, 2000Borato-1,2-diaminocyclohexane platinum (II) (BDP) was synthesized and compared to cisplatin (cisPt) as a potential anti-tumor drug. BDP and cisPt (0.2-20 microM) dose-dependently inhibited DNA synthesis in L1210 murine leukemia cells, DU-145 prostate cancer cells, A549 lung carcinoma cells, and MCF-7 breast cancer cells, as judged by measuring [(3)H ...

Nickel Complexes of Bidentate [S2] and [SN] Borato Ligands
Inorganic Chemistry, 2002Nickel(II) complexes of the monoanionic borato ligands [Ph2B(CH2SCH3)2] (abbreviated Ph2Bt), [Ph2B(CH2S(t)Bu)2] (Ph2Bt(tBu)), [Ph2B(1-pyrazolyl)(CH2SCH3)], and [Ph2B(1-pyrazolyl)(CH2S(t)Bu)] have been prepared and characterized. While [Ph2Bt] formed the square planar homoleptic complex, [Ph2Bt]2Ni, the larger [S2] ligand with tert-butyl substituents ...
