Synthesis and crystal structure of [Ru3Pt(µ-PPh2)(µ4-η2-CCBut)(CO)7(dppe)](dppe = Ph2PCH2CH2PPh2), a butterfly cluster containing an unusually bonded alkynyl ligand: a model for an intermediate molecular geometry in a cluster-ligand rearrangement

Abstract: Reaction of [Ru3Pt(µ-H)(µ4-η2-CCBut)(CO)9(L2)]la(L2= dppe) with Ph2PCCPPh2 affords the butterfly cluster [Ru3Pt(µ-PPh2)(µ4-η2-CCBut)(CO)7(dppe)]3; the metal skeleton and µ4-η2 alkynyl coordination mode in 3 represent a likely model for a transition geometry in the interconversion of 1 and its vinylidene tautomer [Ru3Pt{µ4-η2-CC(H)But}(CO)9(L2)]2.

Synthesis and crystal structure of [MnII(H3L)(L)MnIV][PF6]3[H3L =N,N′,N″-tris-(2S)-2-hydroxypropyl-1,4,7-triazacyclononane]: a mixed-valence pendant-arm macrocycle dimer in which the ligand adopts different angular geometries at the two metal centres

Abstract: Reaction of N,N′,N″-tris-(2S)-2-hydroxypropyl-1,4,7-triazacyclononane (H3L) with MnCl2 in neutral or slightly basic conditions affords (MnII(H3L)(L)MnIV][PF6]3, a mixed-valence, hydrogen-bridged dimer in which the MnIV half has pseudooctahedral geometry and the MnII half has trigonal prismatic geometry.

Synthetic and structural studies on Group 13 complexes containing the M(CO)3(η-C5H5) fragment (M = Cr or Mo). Part 2. Complexes [InClx{M(CO)3(η-C5H5)}2]n–(x= 1, n= o; x= 2, n= 1)

Abstract: The synthesis and solution infrared studies of a range of compounds of general formula [InX(L){M(CO)3(η-C5H5)}2] have been performed where X = Cl or I, L = X, tetrahydrofuran (thf), pyridine (py) and M = Cr, Mo or W. In addition, structures have been determined by X-ray analysis for [InCl(thf){Mo(CO)3(η-C5H5)}2], [InCl(py){Cr(CO)3(η-C5H5)}2] and [NMe4][InCl2{Mo(CO)3(η-C5H5)}2] and these are discussed and compared with the structures of related complexes.

Synthetic and Structural Studies on Cobalt Carbonyl Complexes Containing Indium.

Abstract: The reaction between InCl3 and one equivalent of K[Co(CO)3(PPh3)] affords the complex [InCl2(PPh3){Co(CO)4}] (8), which
