A series of eta3-indenyl molybdenum compounds [(eta3-4,7-Me2C9H5)Mo(CO)2(N,NL)Cl] (N,NL = bpy, phen, pyma), isostructural with well-known eta3-allyl compounds, was synthesized from the recently established halide synthon [{(eta5-4,7-Me2C9H5)Mo(CO)2(mu-Cl)}2]. The low stability of the hexacoordinated eta3-indenyl molybdenum species in solution has been overcome by a modification of the chelating ligand. Hence, the dissociation of the compounds bearing ligands with methyl groups beside nitrogen donor atoms (e.g. 6,6?-Me2-bpy, 2,9-Me2-phen; 2,9-Me2-4,7-Ph2-phen) is strongly disfavored due to the steric requirements of the substituents. The considerable discrimination of the pentacoordinated species enables the use of [(eta5-4,7-Me2C9H5)Mo(CO)2(2,9-Me2-phen)][BF4] for the assembly of derivatives bearing other halides and pseudohalides in the coordination sphere of molybdenum. The current study further describes some other new indenyl complexes accessible from [{(eta5-4,7-Me2C9H5)Mo(CO)2(mu-Cl)}2]. All structural types presented in this experimental study were supported by X-ray crystallographic data.

Bidentate ligands 2,2?-biquinoline (biq) and 6,6?-dimethyl-2,2?-bipyridine (dmbpy) with steric hindrance substituents cis to the nitrogen atoms have been used in the synthesis of transition metal complexes. Six new doubly end-on azido-bridged binuclear complexes [M2(biq)2(mu1,1-N3)2(N3)2] (M = Ni (1), M = Co (2)), [M2(biq)2(mu1,1-N3)2Cl2] (M = Ni (3), M = Co (4)), [M2(dmbpy)2(mu1,1-N3)2(N3)2] (M = Ni (5), M = Co (6)) and one end-to-end thiocyanato-bridged polymeric [Ni(dmbpy)(mu1,3-SCN)(NCS)]n (7) have been synthesized and characterized by single crystal X-ray diffraction analysis and magnetic studies. Complexes 1-6 comprise five-coordinate M(II) ions bridged by two end-on azide ligands. The bridging M-N-M bond angles are in the small range 104.1-105.2. Complex 7 consists of a singly thiocyanate-bridged Ni(II) chain in which Ni(II) ions are five-coordinate. This research suggests that the bulky ligands play a key role in the formation of five-coordinate coordination structure. All complexes display intramolecular intermetallic ferromagnetic coupling with JNiNi and JCoCo of ca. 23 or 13 cm-1 based on the Hamiltonian over(H, ^) = – 2 J over(S, ^)1 over(S, ^)2 (S1 = S2 = 1 for Ni2, or 3/2 for Co2). The singly SCN–bridged chainlike complex 7 shows intrachain ferromagnetic interaction with J = 3.96(2) cm-1 and D = -4.55(8) cm-1 (over(H, ^) = – 2 J ?i = 1 (over(S, ?)i over(S, ^)i + 1) – D ?i = 1 [(over(S, ^)iZ)2 – 2 / 3]). Magneto-structural correlationship has been investigated.

The stability of a variety of bidentate N-base adducts of MoO 2Cl2 and (CH3)ReO3 (MTO) was investigated in thf and CH2C12 as solvents. The formation constants were determined from the spectrophotometric data based on 1:1 adduct formation. The adduct formation constants for [MoO2Cl 2L2](L2 = bidentate nitrogen ligand) are 104-106 times higher than those for [(CH 3)ReO3L2] with the same ligands under the same conditions. The adduct stability of both systems is very sensitive to the electronic nature of the ligands and increases with their donor ability. Hammett correlations of the formation constants against sigmagive relatively large negative values for the reaction constants (pRe = -5.9, p Mo = -6.6). The stability is also governed by steric and strain factors. Thus, sterically hindered 6,6′-disubstituted 2,2′ -bipyridines do not form ad ducts with MTO, and only 6,6′-dimethyl- and 6,6′-diphenyl- 2,2′-bipyridines form adducts with MoO2Cl2. However, these adducts are much less stable than other methyl derivatives of 2,2′-bipridine adducts. The steric strain between the two methyl groups in 3,3-dimethy 1-2,2′-bipyridine influences the bipyridine planarity upon complexation and reduces the adduct stability. The thermodynamic parameters (enthalpy and entropy) were determined from temperature-dependence studies. The adduct stability is mainly due to the strongly exothermic binding of the nitrogen-bidentate ligand. The entropy change is small and has little effect on adduct stability.Wiley-VCH Verlag GmbH & Co, KGaA.
