Source of material
All chemicals and solvents were used as purchased without further purification. The melting point was determined using a Mel-temp II digital melting point apparatus and was uncorrected. The IR spectrum was obtained on a Bruker Vertex 70v FTIR Spectrometer in the scan range 4000–400 cm−1. The 1H NMR spectrum was recorded at room temperature in CDCl3 solution on a Bruker Ascend 400 MHz NMR spectrometer with chemical shifts relative to tetramethylsilane.
The Schiff base ligand was synthesised from the reaction of benzoylacetone (Sigma Aldrich) and 2-hydroxybenzhydrazide (Fluka) in a 1:1 molar ratio. Bis(acetylacetonato)dioxomolybdenum(VI) (Sigma Aldrich, 0.33 g, 1 mmol) and the prepared Schiff base were dissolved in methanol (30 mL) and the mixture was refluxed for 2 h. After filtration, the filtrate was evaporated slowly until yellow crystals were formed. The crystals were filtered, washed with a minimum amount of methanol and air-dried in vacuo over P4O10. Yield: 0.20 g (40%). M.pt: 469–471 K.

Experimental details
The C-bound H atoms were geometrically placed (C—H = 0.95–0.98 Å) and refined as riding with Uiso(H) = 1.2–1.5Ueq(C). The O-bound H-atom was also geometrically placed (O—H = 0.84 Å) and refined as riding with Uiso(H) = 1.5Ueq(O).
Comment
The study of di-oxido-molybdenum complexes with di-anionic tridentate ligands is particularly significant as the coordination environment of the [MoO2]2+ core is known to be crucial as an open active site for catalytic oxidation processes [5], [6]. In this work, the synthesis and crystal structure analysis of the title complex, Mo(=O)2(L)(O=SMe2), (I), where H2L is 2-hydroxy-N-[(2Z)-4-hydroxy-4-phenylbut-2-en-2-yl] benzenecarbohydrazonic acid, with a slight modification of the Schiff base ligand employed in earlier reported work [7], is described in continuation of on-going studies in this area [7], [8], [9].
The mononuclear title complex in (I) is shown in the figure (70% probability displacement ellipsoids). The Mo(VI) centre is complexed by O1, O3 and imine-N2 atoms, derived from the tridentate Schiff base di-anion, the oxido-O4 and O5 atoms as well as the O6 atom of the dimethylsulphoxide ligand [10]. This results in a N2O4 donor set that defines an approximate octahedral geometry in which the oxido groups are cis to each other, and where the three donor atoms of the L2− anion occupy meridional positions. The O1—Mo—O3 angle [149.93(6)°] deviates significantly from linearity, which is due mainly to the acute angles subtended by the five-[O1—Mo—N2 = 72.54(6)°] and six-membered [O3—Mo—N2 = 82.32(6)°] chelate rings owing to the tridentate mode of coordination of the Schiff base di-anion. Each of the five- and six-membered chleate rings adopts an envelope configuration with the Mo atoms being the flap atom. In the smaller chelate ring, the Mo flap atom lies 0.106(3) Å out of the plane defined by the four remaining atoms (r.m.s. deviation = 0.0014 Å). In the larger chelate ring, the envelope configuration is significantly more pronounced with the Mo atom lying 0.446(3) Å out of the least-squares plane defined by the five remaining atoms of the chelate ring (r.m.s. deviation = 0.0158 Å). The dihedral angle formed between the least-squares planes through the chelate rings is 9.37(5)°. The dihedral angles between the five-membered chelate ring and the pendent hydroxyphenyl ring is 10.94(6)°, between the six-membered ring and adjacent phenyl ring is 2.45(6)°, and between the hydroxyphenyl and phenyl rings is 7.58(6)°. Thus, to a first approximation, the Schiff base ligand is planar. An intramolecular loop – S(6) graph set – is evident owing to the formation of a hydroxy-O—H⋯N(imine) hydrogen bond [O2—H2O⋯N1: H2O⋯N1 = 1.837(19) Å, O2⋯N1 = 2.619(2) Å with angle at H2O = 151(3)°].
In the crystal of (I), C—H⋯O interactions connect complexes into a three-dimensional architecture. Thus, hydroxyphenyl, phenyl- and imine-methyl-C—H⋯O(oxo) [C6—H6⋯O4i: H6⋯O4i = 2.52 Å, C6⋯O4i = 3.239(3) Å with angle at H6 = 132°; C14—H14⋯O5ii: H14⋯O5ii = 2.60 Å, C14⋯O5ii = 3.333(3) Å with angle at H14 = 135° and C9—H9c⋯O4iii: H9c⋯O4iii = 2.53 Å, C9⋯O4iii = 3.449(3) Å with angle at H9c = 157° for symmetry operations (i) x, 3/2 − y, −1/2 + z, (ii) 3/2 − x, 1 − y, 1/2 + z and (iii) 3/2 − x, −1/2 + y, z] interactions lead to the formation of a supramolecular layer in the bc-plane. The coordinated dimethylsulphoxide groups protrude to either side of the layer and inter-digitate with neighbouring layers with the connections between them being of the type dimethylsulphoxide-C—H⋯O(oxide) [C18—H18b⋯.O1iv: H18b⋯.O1iv = 2.60 Å, C18⋯.O1iv = 3.331(3) Å with angle at H18b = 131° for (iv) 1 − x, 1/2 + z, 1/2 − z].
Further analysis of the molecular packing was conducted with Crystal Explorer 17 [11] to calculate the Hirshfeld surfaces of (I) along with the full and delineated two-dimensional fingerprint plots following literature precedents [12]. This analysis showed, reflecting the formation of many C—H⋯O contacts in the crystal, that O⋯H/H⋯O contacts amounted to 30.7% of all contacts on the calculated Hirshfeld surface, approaching the 41.3% contributed by H⋯H contacts. The C⋯H/H⋯C contacts to the surface, at 15.7%, were also prominent with smaller but, notable C⋯C [4.8%], N⋯H/H⋯N [2.1%], O⋯C/C⋯O [1.6%] and N⋯C/N⋯C [1.4%] contacts. However, these occur at separations greater than the sum of the respective van der Waals radii.
