Di-μ3-oxido-di-μ2-oxido-tetraoxidobis(1,1,2,2-tetramethylethylenedicyclopentadienyl)dimolybdenum(IV)dimolybdenum(VI) hexahydrate
The title compound, [Mo(4)(C(16)H(20))(2)O(8)]·6H(2)O, is a centrosymmetric ansa-molybdocene complex in which two dinuclear [C(2)Me(4)(η(5)-C(5)H(4))(2)]Mo(μ(2)-O)(2)MoO(2) units dimerize by forming two μ(3)-O bridges between three Mo atoms. The ansa-molybdocene [C(2)Me(4)(η(5)-C(5)H(4))(2)]Mo unit has a typical bent-sandwich metallocene structure with an inter-ring angle of 127.98 (8)°. The Mo...
متن کاملHexakis(2-aminopyridinium) di-μ6-oxido-tetra-μ3-oxido-tetradeca-μ2-oxido-octaoxidodecavanadium(V) dihydrate
In the title compound, (C(5)H(7)N(2))(6)[V(10)O(28)]·2H(2)O, the [V(10)O(28)](6-) anion is generated by crystallographic inversion symmetry and each of the five vanadium centres adopts a distorted VO(6) octa-hedral geometry. In the crystal structure, a network of N-H⋯O, N-H⋯(O,O) and O-H⋯O hydrogen bonds helps to establish the packing.
متن کاملHexakis(dimethylammonium) di-μ6-oxido-tetra-μ3-oxido-tetradeca-μ2-oxido-octaoxidodecavanadate(V) monohydrate
In the title compound, (C(2)H(8)N)(6)[V(10)O(28)]·H(2)O, the [V(10)O(28)](6-) polymetalate anion has crystallographic mirror symmetry with six V atoms and 12 O atoms lying on the mirror plane. Each of the V(V) atoms adopts a distorted octa-hedral geometry. Eight terminal O atoms are bonded to V(V) atoms with double bonds and the others act as bridging atoms. In the crystal structure, a network ...
متن کاملPoly[[2-(3-pyridinio)-1H,3H +-benzimidazolium] [μ4-oxido-di-μ3-oxido-tetra-μ2-oxido-hexaoxidotetramolybdenum(VI)]]
The reaction of MoO(3) with 2-(3-pyrid-yl)benzoimidazole and water in the presence of MnSO(4)·5H(2)O at 453 K under hydro-thermal conditions afforded the title compound, {(C(12)H(11)N(2))[Mo(4)O(13)]}(n), in which infinite molybdenum oxide anionic chains are charge-balanced by diprotonated 2-(3-pyrid-yl)benzoimidazole (H(2)3-PBIM(2+)) cations. Eight [MoO(6)] octa-hedra are edge-shared, forming ...
متن کاملDichloridooctakis(4-chlorobenzyl)di-μ2-hydroxido-di-μ3-oxido-tetratin(IV) toluene solvate
The title stannoxane is a toluene-solvated dimer, [Sn(4)(C(7)H(6)Cl)(8)Cl(2)O(2)(OH)(2)]·C(7)H(8), the tetra-nuclear mol-ecule lying across a center of inversion. The Sn(4)O(4) framework, whose two independent Sn atoms show trigonal bipyramidal coordination, is essentially planar (r.m.s deviation = 0.02 Å). One of the two chloro-benzyl groups of the chloridodiorganyltin unit is disordered over ...
