Bis(tetraphenylphosphonium) tetraiodidomanganate(II) acetone monosolvate
The title compound, (C(24)H(20)P)(2)[MnI(4)]·(CH(3))(2)CO, prepared from the reaction of manganese powder, iodine and tetra-phenyl-phospho-nium iodide in acetone shows a tetra-hedral complex anion [Mn-I = 2.6868 (5)-2.7281 (4) Å and I-Mn-I = 104.011 (13)-116.164 (15)°], two tetra-phenyl-phospho-nium cations and one mol-ecule of acetone.
متن کاملBis(2,6-dicarboxypyridinium) dichloride acetone monosolvate
The title compound, 2C(7)H(6)NO(4) (+)·2Cl(-)·C(3)H(6)O, crystallizes with two 2,6-dicarboxy-pyridinium cations, two chloride anions and one acetone mol-ecule in the asymmetric unit. The crystal structure is characterized by alternating cations and by Cl(-) anions, forming zigzag chains running along the a axis.
متن کاملReaction of 1-alkylthioisoquinolinium salts with active methylene compounds.
2-Alkyl-1-alkylthioisoquinolinium salts were readily prepared from 2-alkyl-1(2H)-isoquinolones via 2-alkyl1(2H)-thioisoquinolones in two steps. Under mild conditions, the reaction of 2-alkyl-1-alkylthioisoquinolinium salts with active methylene compounds in the presence of sodium hydride afforded 2-alkyl-1-(substituted methylene)iso-quinolines in good yields. Pyrrolo[2,1-a]isoquinolines were sy...
متن کامل3,5-Bis(2,4-dinitrophenyl)-4-nitro-1H-pyrazole acetone monosolvate
The title structure, C(15)H(7)N(7)O(10)·C(3)H(6)O, was prepared by penta-nitration of 3,5-diphenyl-1H-pyrazole. The proton attached to a pyrazole N atom forms a hydrogen bond with the O atom of the acetone solvent mol-ecule, owing to the NO(2) enhanced acidity of the proton. The NO(2) group on the phenyl C atom is twisted by 33.9 (2)° from coplanarity with the ring in order to avoid a short int...
متن کاملBis(acetone 4-phenylthiosemicarbazonato-κ2 N 1,S)zinc(II)
The Zn(II) atom in the title compound, [Zn(C(10)H(12)N(3)S)(2)], is N,S-chelated by the deprotonated Schiff base in a tetra-hedral environment. The metal atom lies on a twofold rotation axis that relates one anion to the other. The amino H atom forms an intermolecular N-H⋯π inter-action to an aromatic ring.
