Source of material

The ligand, 3-ethoxysalicylaldehyde 3-methoxybenzoic hydrazone was prepared from the 1:1 molar reaction of 3-ethoxysalicylaldehyde (Merck) and 3-methoxybenzoic hydrazide (Sigma-Aldrich). Next, MoO2(acetylacetonate)2 (Sigma-Aldrich; 0.33 g, 1 mmol) was added to the freshly prepared Schiff base ligand (1 mmol, 0.302 g) in methanol (40 mL). The resulting solution was refluxed for 3 h. The filtrate was evaporated until a beige precipitate was obtained. The precipitate was recrystallised from acetone-methanol by slow evaporation to yield brown crystals. The mixture was refluxed for 2 h. The title compound was isolated from the recrystallisation of the complex in DMSO. Yield: 0.32 g (63.5%).

Experimental details

The C-bound H atoms were geometrically placed (C—H = 0.95–0.99 Å) and refined as riding with Uiso(H) = 1.2–1.5Ueq(C).

Comment

It is now well established that the sixth coordination site in mononuclear dioxidomolybdenum(VI) complexes of ONO-donor Schiff base dianions is labile [5], [6], [7], [8], with exchange between different molecules, e.g. solvent, often observed. Further interest in these molecules arises as a result of investigations of putative anti-cancer potential [6], [8]. In continuation of structural studies of Mo complexes of Schiff bases [6], [9], [10], the title complex, (I), with a coordinated DMSO molecule, was investigated crystallographically with a further analysis of the molecular packing performed through the calculated Hirshfeld surfaces. The molecular structure of (I) is shown in the figure (70% displacement ellipsoids).

The Mo atom is coordinated within a NO5 donor set defined by cis-oxo atoms [Mo—O5, O6 = 1.7003(12), 1.7145(12) Å] a DMSO-O [Mo—O7 = 2.2872(12) Å], and enolic-O [Mo—O1 = 2.0029(12) Å], phenolate-O [Mo—O2 = 1.9325(12) Å] and imine-N [Mo—N2 = 2.2337(14) Å] atoms of the di-negative, tridentate Schiff base ligand. The longer Mo—O6(oxo) bond has the O6 atom approximately trans [160.75(6)°] to the imine-N2 atom, and the more strongly bound oxo-O5 atom trans to the weakly-bound DMSO-O7 atom. The other trans angle in the six-coordinate geometry which approximates an octahedron is 150.01(5)°, for the O1—Mo—O2 angle. In this description, the Mo atom lies 0.3037(7) Å out of the basal plane defined by the O1, O2, O6 and N2 [r.m.s. deviation = 0.0091 Å] in the direction of the O5 atom.

The mode of coordination of the Schiff base di-anion leads to the formation of five- and six-membered chelate rings. The five-membered ring is planar, exhibiting a r.m.s. deviation of 0.0057 Å for the fitted atoms with the maximum deviation being 0.0083(8) Å for the O1 atom.

By constrast, the six-membered ring is non-planar and is best described as being based on an envelope with the Mo atom, the flap, lying 0.486(2) Å above the plane of the five remaining atoms [r.m.s. deviation = 0.0379 Å] with a maximum deviation = 0.0550(12) Å for atom C2. The dihedral angle between the five-membered chelate ring and the planar region of the six-membered ring is 11.25(9)°. The dihedral angle between the outer aromatic rings is 5.61(9)°.

The most closely related structure in the literature is of the analogue where the ethoxy substituent of (I) is methoxy [8]. As would be anticipated, the same trends in geometric parameters are evident.

Non-covalent C—H⋯O intermolecular interactions provide specific points of contact between molecules in the crystal of (I). The acceptor atoms are oxo-O5 and -O6 exclusively with the former forming three contacts and the later, two. The donor atoms are imine-C—H, phenyl-C—H, methoxy-C—H and DMSO-methyl-C—H [range of H⋯C = 2.42 to 2.58 Å and range of angles at H = 118 to 133°].

A further analysis of the molecular packing was performed by calculating the Hirshfeld surface as well as the full- and delineated two-dimensional fingerprint plots, following standard protocols [11] and the program Crystal Explorer 17 [12]. The analysis confirms the importance of C—H⋯O interactions in contributing to the stability of the crystal, contributing 30.8% of all surface contacts, and second only to H⋯H contacts, i.e. 43.0%. The other major contribution to surface contacts, at 16.8%, comes from C⋯H/H⋯C contacts. The only other contacts making over 1% contributions to the Hirshfeld surface are H⋯H/H⋯N [2.7%], N⋯C/C⋯N [1.8%] and C⋯C [1.6%].
