(Received 3 April 2012; accepted 25 April 2012; online 2 May 2012)

The asymmetric unit of the title compound, [RhCl2(C10H8N2)2]ClO4, consists of one unit of the cationic complex [RhCl2(bipy)2]+ and one uncoordinated perchlorate anion. The RhIII atom is coordinated by four N atoms from two bipyridyl ligands and two Cl atoms, forming a distorted octa­hedral environment. The Cl ligands are cis. Two intramolecular C—H⋯Cl hydrogen bonds occur in the cationic complex . In the crystal, mol­ecules are linked together by a hydrogen-bond network involving the H atoms of bipyridyl rings and perchlorate anions. An O atom of the perchlorate anion is disordered over two sites, with an occupancy-factor ratio of 0.78 (3):0.22 (3).

Comment top

In recent years, noble metal complexes of pyridyl ligands have received much attention because of their rich electrochemical (Rasmussen et al., 1990, photophysical (Forster & Rund, 2003) and photochemical (Arachchige et al., 2008) properties, and their potential applications in catalysis (Mbaye et al., 2003), biochemistry (Tan et al., 2005; Chifotides et al., 2004) and anticancer activity (Karidi et al., 2005). Bipyridine (bipy) is one of the most commonly used bidentate ligand of this type in the formation of wide variety of transition metal complexes with a general formula of [MII(bipy)2X2] (M = Co, Ni, Mn, Fe) in which X is an coordinated anionic ligand such as CN, SCN and chloride (De Munno et al., 1993; Eggleston et al., 1985; Kramer & Straehle, 1986; Al-Noaimi and Haddad, 2007; Fontaine, 2001; Choudhury et al., 2006; Gao & Ng, 2010) and complexes with cationic part [MIIICl2(bipy)2]+ (M = Re, Ru, Co, Ga) and any counter anion like Cl-, PF6- (Figgis et al., 1985; Sofetis et al., 2006; Andansen & Josephsen, 1971; Strenger et al., 2000; Kim et al., 2009; Prajapati et al., 2008; Helberg et al., 1996). The complex [RhCl2(bipy)2]Cl.2H2O has also been obtained and crystallographycaly determined by Lahuerta et al., 1991. Yet, no crystal structure has been reported for the cationic complex cis-[Rh(bipy)2Cl 2]+ in its perchlorate form as counter anion, therefore, we report the crystal structure of compound (I).

Complex (I) crystallizes in the orthorhombic space group P212121. The molecular structure of (I) depicted in Figure 1. It has a distorted octahedral geometry with the two chloride ions in cis positions. Selected bond lengths for the complex are given in Table 1. The Rh–N axial bond distance (2.038 (3) Å) is slightly longer than Rh–N equatorial bonds (average 2.026 (5) Å). Its may be well compared with the negligible difference between equatorial and axial M–N bonds distances seen in the analogous complexes of platinum metal group (Lahuerta et al., 1991; Kim et al., 2009; Helberg et al., 1996; Prajapati et al., 2008; Eggleston et al., 1985), but greater distortion observed in majority of transition metal complexes (Strenger et al., 2000; Fontaine, 2001; Kramer & Straehle, 1986; Sofetis et al., 2006; Figgis et al., 1985; Choudhury et al., 2006; Gao & Ng, 2010). The Rh–Cl bond distances in (I) are 2.3291 (9) (equatorial) and 2.3344 (9) Å (axial). The Neq–Rh–Neq angle is 174.22 (10)° and its distorted from linearity by approximately 6 °. Also Cleq–Rh–Clax angle (91.18 (4) °) is nearly octahedral. The cis isomerization of cationic complex [RhCl2(bipy)2]+ is stabilized by short contacts. Coordinated chlorides which situated in cis position to respect to each other make up short contact Cl2···H1 and Cl3···H11 with distances 2.7 and 2.76 Å, respectively (Tabl. 2). The crystal lattice of (I) is made up of well separated ClO4- anions and [RhCl2(bipy)2]+ cations. The perchlorate anion contribute to forming extensive hydrogen bonding net linked together cationic and anionic parts of the structure. The interactions involve the hydrogen bonding between H atoms of bipy ring with oxygen atoms uncoordinated perchlorate anion. Each oxygen atoms participates in four hydrogen bonds to H atoms of aryl groups (Tabl. 2). The atom O2 of the perchlorate anion is disordered and splited over two sites with refined occupancy ratio of 0.78 (3):0.22 (3).

Experimental top

To a solution of RhCl3.xH2O (0.05 g, 0.231 mmol) and KClO4 (0.09 g, 0.693 mmol) in H2O (10 ml) was added 2,2'-bipyridine (0.04 g, 0.462 mmol) in CH3OH (10 ml), and was stirred for 2 h to yellow solution resulted. Yellowish rhombohedral crystals suitable for X-ray analysis were obtained by slow evaporation during two weeks. RhCl3.xH2O purchased from Johnson Matthey, all other reagents was obtained commercially from Sigma-Aldrich and used without futher purification.

Refinement top

H atoms were positioned geometrically and allowed to ride on their respective parent atoms [C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C)]. The value of the Flack parameter, 0.47 (3) suggests that the crystal is a racemic twin.

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