N-(Diphenyl-carbamo-yl)-N,N',N',N'',N''-penta-methyl-guanidinium tetra-phenyl-borate.

ABSTRACT: In the title salt, C19H25N4O(+)·C24H20B(-), the C=N and C-N bond lengths in the CN3 unit are 1.3327?(8)/1.3364?(9) and 1.3802?(9)?Å, indicating double- and single-bond character, respectively. The N-C-N angles are 118.77?(6), 120.29?(6) and 120.81?(6)°, showing only a small deviation of the CN3 plane from an ideal trigonal-planar geometry. The bonds between the N atoms and the terminal methyl C atoms all have values close to a typical single bond [1.4636?(9)-1.4772?(9)?Å]. The crystal packing is caused by electrostatic inter-actions between cations and anions.

Project description:The structure of the title compound, [Ru(C(10)H(15))(C(13)H(10)O)](C(24)H(20)B), consists of discrete [Cp*Ru(II)benzophenone] cations and tetra-phenyl-borate anions (Cp* = penta-methyl-cyclo-penta-dien-yl). Tethering the Cp*Ru group to one aryl ring of benzophenone results in average values of 1.42?(1) and 1.38?(1)?Å for the C-C bond lengths in the Ru-tethered and untethered phenyl rings, respectively. The dihedral angle between the benzene and phenyl rings of the benzophenone group is 50.5?(1)°.

Project description:The title compound, [Ru(C(10)H(15))(C(10)H(12)O)][B(C(6)H(5))(4)], crystallizes as discrete (?(5)-penta-methyl-cyclo-penta-dien-yl)Ru(?(6)-4-phenyl-butan-2-one)](+) cations and [BPh(4)](-) anions. In the cation, the non-H atoms of the butan-2-one group are approximately planar (r.m.s. deviation = 0.056?Å) and lie nearly perpendicular to the plane of the phenyl ring with a dihedral angle between the two planes of 69.3?(1)°. No significant C-H?O inter-actions are observed between the methyl and phenyl H atoms and the carbonyl O atom.

(?-Isopropyl N-phenyl-carbamate)(?-penta-methyl-cyclo-penta-dien-yl)ruthenium(II) tetra-phenyl-borate acetone monosolvate.

Project description:The title complex, [Ru(C(10)H(15))(C(10)H(13)NO(2))](C(24)H(20)B)·C(3)H(6)O, is related to the analogous O-methyl complex. The average Ru-C distance to the penta-methyl-cyclo-penta-dienyl (Cp*) group is 2.19?(3)?Å, and 2.21?(1)?Å to the ortho, meta and para C atoms of the arene ring. The Ru-C(ipso) bond length of 2.272?(3)?Å is significantly longer, reflecting movement of the Ru atom away from the C atoms with electronegative substituents attached. The amide H atom in the cation forms an inter-molecular N-H?O hydrogen bond with the carbonyl O atom of the acetone solvent mol-ecule. A C-H?O inter-action also occurs.
