(Received 12 September 2011; accepted 13 September 2011; online 17 September 2011)

In the title compound, [HgI2(C23H14N4O)], the HgII atom is four-coordinated by two N atoms from one 1-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)naphthalen-2-ol ligand and by two I atoms in a distorted tetra­hedral environment. An intra­molecular O—H⋯N hydrogen bond stabilizes the mol­ecular conformation and an inter­molecular N—H⋯I inter­action stabilizes the crystal packing.

Supporting information


Comment top

The ligand 1-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)naphthalen-2-ol) is a N-donor ligand and has excellent coordinating ability (Wang et al., 2010). In this work, we selected it as an N-donor chelating ligand, generating a new HgII complex.

In the compound, the central HgII atom is four-coordinated by two N atoms from one organic ligand, and two I atoms in a distorted tetrahedral sphere. N-H···I and O-H···N H-bonding interactions stabilize the crystal structure and the molecular conformation.

Experimental top

A mixture of HgI2 (0.5 mmol) and 1-(1H-imidazo[4,5-f][1,10]phenanthrolin-2-yl)naphthalen-2-ol) (0.5 mmol) in 8 mL distilled water was heated at 462 K in a Teflon-lined stainless steel autoclave for seven days. The reaction system was then slowly cooled to room temperature. Pale yellow crystals of the title compound suitable for single crystal X-ray diffraction analysis were collected from the final reaction system by filtration, washed several times with distilled water and dried in air at ambient temperature. Yield: 15% based on Hg(II).

Refinement top

H atoms bonded to N and C were positioned geometrically (C-H = 0.93 Å) and refined as riding, with Uiso(H)=1.2Ueq(carrier). The H atom bonded to O was freely refined.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2sigma(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
