Source of material

The mixture of Ni(OAc)2·4H2O (0.1 mmol) and N 4-methyl-S-methylisothiosemicarbazide-hydrogeniodide, L·HI, (0.2 mmol) is disolved in warm EtOH (5 mL). The solution is spontaneously evaporated to a small volume. Bluish-purple single crystals are filtered and washed with EtOH. Non-commercial ligand L·HI is obtained in the reaction of N 4-methyl-thiosemicarbazide and methyl-iodide in absolute ethanol during reflux for 45 min.

Experimental details

The used crystal specimen was a non-merohedral twin. Upon determination of the twin law, simultaneous integration of reflecton intensities was performed. Deconvoluted intensity data (SHELX HKLF 4 format) were used for structure solution, while refinement was performed against 4152 merged reflections in SHELX HKLF 5 format.

Coordinates of carbon-bonded hydrogen atoms were introduced in idealized positions and refined using riding model. Their U iso values are approximated as U iso = kU eq of the parent atom (k = 1.2 for sp 2 and 1.5 for sp 3 hybridized atoms). Locations of hydrogen atoms bonded to heteroatoms were determined from residual electron density maps and were refined with distance restraints. Their U iso values are approximated as U iso = kU eq of the parent atom (k = 1.2 for nitrogen- and 1.5 for oxygen-bonded atoms). Non-coordinated water molecule was refined as a rigid group.

Comment

Introduction

Numerous complexes of transition metals with derivatives of S-alkylisothiodemicarbazide are synthesized and characterized by single crystal X-ray diffraction [5]. Besides the interesting metal-induced reactions of ligands and unusual open chain and macrocyclic structures, some of these tetra- and octadentate ligands can stabilize Cu(III), Ni(III), and Fe(IV) ions [6], [7], [8], [9], [10].

In Refs. [11, 12] the structure of trans-square-planar Ni(II) complex with NN bidentate S-methylisothiosemicarbazide (L1), i.e. [Ni(L1)2]I2 is described. This complex is obtained in the reaction of EtOH solutions of Ni(OAc)2·4H2O and L1·HI in a 1:2 M ratio. In this paper, it is shown that under the same synthetic conditions, the reaction of Ni(OAc)2·4H2O and L·HI results in the formation of the trans-octahedral complex of the formula [NiL2(H2O)2]I2·0.5H2O.

Structural comment

The asymmetric unit of [NiL2(H2O)2]I2·0.5H2O consists of half of the complex cation situated at a special position of site symmetry 1 ‾ , one iodide ion, and a half water molecule with 0.5 site occupancy factor situated at two-fold rotation axis. Complex cation [NiL2(H2O)2]2+ consists of two NN bidentate N 4-methyl-S-methylisothiosemicarbazide ligands situated in the equatorial plane, and two water molecules occupying axial positions of an octahedrally coordinated Ni(II) atom, and has an approximate 2/m symmetry (r.m.s.d. of atomic positions from symmetrized structure is 0.139 Å). Similar cation is observed in complex [Ni(L1)2(H2O)2](tph)·2H2O, where H2tph is terephthalic acid [13]. Metal–ligand bond lengths and valence angles within the coordination polyhedron of these two structures match within ±0.02 Å, and ±1°, respectively. As expected for Ni(II) octahedral complexes, axial metal–ligand bond lengths are longer (d(Ni1—O1) = 2.147(3) Å) compared to equatorial (d(Ni1—N1) = 2.095(4) and d(Ni1—N4) = 2.046(4) Å).

As already mentioned, the constitution of complex cation in [NiL2(H2O)2]I2·0.5H2O is different from that found in [Ni(L1)2]I2 [11, 12], even though syntheses were conducted under equivalent conditions. Significant differences are observed when metal–ligand bond lengths are compared to [Ni(L1)2]I2, where nickel(II) is in a square-planar environment composed of two S-methylisothiosemicarbazide ligands. Namely, in [Ni(L1)2]I2, both metal ligand bonds are shorter, and the chelate bite angle is larger. On the other hand, intraligand bond lengths of the common type in all mentioned complexes have similar values. This indicates that methylation of N4 did not significantly change the ligand structure.

A complex network of hydrogen bonds is present in the crystal structure, where all potential hydrogen bond donors are involved in bonding.
