The reaction of 5-(1-adamantyl)-3-methyl-1H-pyrazole with dibromomethane yields a product mixture bis(3-adamantyl-5-methylpyrazolyl)methane (H2C(PzAd,Me)2, 2 a), (3-adamantyl-5-methylpyrazolyl)-(3-methyl-5-adamantylpyrazolyl)methane ((H2C(PzAd,Me)(PzMe,Ad), b) and bis(3-methyl-5-adamantylpyrazolyl)methane (H2C(PzMe,Ad)2, c). Lithiation sterically congested H2C(PzAd,Me)2 (2 a) subsequent additio...

Reaction of the tricarbon-yl{η(5)-[2-(dimethyl-amino)eth-yl]cyclo-penta-dien-yl}molybdenum anion and dichlorido-diphenyl-stannane affords the title compound, [MoSn(C(6)H(5))(2)Cl(C(9)H(14)N)(CO)(3)], which exhibits a four-legged piano-stool geometry with chlorido-diphenyl-stannyl ligands unperturbed by the pendant 2-(dimethyl-amino)ethyl groups. The Mo-Sn bond length [2.7584 (5) Å] and the dist...

In the title centrosymmetric mononuclear Zr(IV) compound, [ZrCl(4){P(O)(C(6)H(5))(2)P(C(6)H(5))(2)}(2)]·C(6)H(6), the central Zr(IV) ion is coordinated by two O atoms from two symmetry-related (diphenyl-phosphino)diphenyl-phosphine ligands and four Cl atoms in a distorted octahedral geometry with the four Cl atoms in the equatorial positions. The mol-ecule lies about a center of inversion and t...

The asymmetric unit of the title compound C25H19N5OS, contains two mol-ecules, A and B. In mol-ecule A, the dihedral angles between the pyrazole ring and the C-bound phenyl group, the N-bound phenyl group and the thia-diazole ring are 32.30 (14), 52.25 (14) and 34.94 (12)°, respectively. The corresponding angles in mol-ecule B are 33.32 (14), 50.67 (15), and 70.30 (12)°, respectively. In the cr...

In the title compound, [Ni(C(20)H(13)O(5)P)(C(12)H(10)N(2))(H(2)O)](n), the Ni(II) cation is coordinated by three O atoms from two 5-(diphenyl-phosphino-yl)isophthalate anions, two N atoms from two 1,2-bis-(pyridin-4-yl)ethene ligands and one water mol-ecule in a distorted octa-hedral geometry. Both 1,2-bis-(pyridin-4-yl)ethene and 5-(diphenyl-phosphino-yl)iso-phthal-ate bridge the Ni(II) catio...
