In the title triangulo-triruthenium compound, [Ru(3)(C(21)H(21)As)(CO)(11)], one equatorial carbonyl group has been substituted by the monodentate arsine ligand, leaving one equatorial and two axial carbonyl substituents on the Ru atom. The remaining two Ru atoms each carry two equatorial and two axial terminal carbonyl ligands. The three arsine-substituted phenyl rings make dihedral angles of ...
In the mononuclear Ti(IV) title complex, [Ti(C29H33NO2)(C3H6O)2], the TiNO4 coordination polyhedron comprises an N-atom and two O-atom donors from the dianionic Schiff base ligand and two O-atom donors from monodentate isopropoxide anions. The stereochemistry is distorted trigonal-bipyramidal with the N-donor in an elongated axial site [Ti-N = 2.2540 (17) Å], the O-donors having normal Ti-O bon...
In the title triangulo-triruthenium compound, [Ru(3)(C(6)H(15)O(3)P)(CO)(11)], each Ru atom has distorted octa-hedral coord-ination geometry. The monodentate phosphine ligand is equatorially coordinated to one Ru atom, leaving one equatorial and two axial carbonyl substituents on the Ru atom. Each of the remaining two Ru atoms carries two equatorial and two axial carbonyl groups. In the crystal...
Axial ligand substitution of a mononuclear nonheme oxoiron(IV) complex, [FeIV(O)(TMC)(NCCH3)]2+ (1) (TMC = 1,4,8,11-tetramethyl-1,4,8,11-tetraazacyclotetradecane), leads to the formation of new FeIV=O species with relatively intense electronic absorption features in the near-UV region. The presence of these near-UV features allowed us to make the first observation of Fe=O vibrations of S = 1 mo...
A new molybdenum porphycene complex, which is a new complex having oxo and chloro groups at the axial positions, was successfully synthesized. This chloro(oxo)molybdenum(v) complex, [Mo(V)(OEPc)(O)Cl] (1) has strong absorption bands in the visible region attributed to the properties of the porphycene and is very attractive from a photochemical viewpoint. This complex was readily reduced from Mo...
In the title triangulo-triruthenium compound, [Ru(3)(C(18)H(12)Cl(3)P)(CO)(11)], one equatorial carbonyl group has been substituted by the monodentate phosphine ligand, leaving one equatorial and two axial carbonyl substituents on the Ru atom. The remaining two Ru atoms each carry two equatorial and two axial terminal carbonyl ligands. The three benzene rings make dihedral angles of 87.83 (17),...
