In the dinuclear title compound, [Cu2I2(C3H8N2S)(C25H22P2)2]·1.5CH3CN, each CuI atom exhibits a distorted tetrahedral coordination with two P atoms from two bis(diphenylphosphanyl)methane (dppm) ligands, one metal-bridging S atom from the 1-ethylthiourea (ettu) ligand and one iodide ion. The dppm ligand and the bridging S atom of the ettu ligand force the two copper atoms into close proximity, leading to the formation of a close intramolecular Cu⋯Cu contact [3.3747 (17) Å]. The conformation of the dimeric complex is such that the two dppm ligands are located on one side of the dinuclear metal complex, while the two iodine atoms are pointed towards the other side of the complex, a conformation that is stabilized by two intramolecular N—H⋯I hydrogen bonds between the ettu NH2 and NHEt moieties and the I atoms. Another pair of symmetry-equivalent N—H⋯I hydrogen bonds is established between neighboring molecules across an inversion center, linking molecules into dimers. The dimers are connected with each other and with the interstitial acetonitrile solvent molecules via a range of weaker C—H⋯I and C—H⋯S interactions and through weak C—H⋯π interactions, leading to the formation of a three-dimensional network. One of the acetonitrile solvent molecules is disordered in a 1:1 ratio across a crystallographic inversion center.

1-Ethylthiourea, ettu, (0.03 g, 0.29 mmol) was dissolved in 30 cm3 of acetonitrile at 348 K and then CuI (0.05 g, 0.26 mmol) was added. The mixture was stirred for 4 h and then bis(diphenylphosphanyl)methane, dppm, (0.1 g, 0.26 mmol) was added and the new reaction mixture was heated under reflux for 12 h where upon the precipitate gradually disappeared. The resulting clear solution was filtered off and left to evaporate at room temperature. The crystalline complex, which was deposited upon standing for several days, was filtered off and dried in vacuo (0.12 g, yield 67%). Mp = 531–533 K. Analysis found: C 47.77, H 4.02, N 3.68, S 2.26%; calculated for C112H113Cu4IN7P8S2: C 51.09, H 4.29, N 3.72, S 2.43%.
The H atoms were positioned geometrically and refined using a riding model, with C—H = 0.95 with Uiso(H) = 1.2 Ueq(C) for H atoms on C(sp2) and 0.98–0.99 Å with Uiso(H) = 1.5 Ueq(C) for H atoms on C(sp3). All H atoms bonded to N atoms were located in a difference Fourier map and refined isotropically, with N—H distances restrained to 0.87 (2) Å with Uiso(H) = 1.2Ueq(N). One of the acetonitrile molecules is disordered in a 1:1 ratio across a crystallographic inversion center and was refined anisotropically.
Metal(I) complexes with mixed phosphine and sulfur donor ligands have attracted much attention in recent years because of various applications based on e.g. their luminescent properties (Safin et al., 2010) or antimicrobial activities (Isab et al., 2010). CuI ions functioning as Lewis acids tend to form covalent bonds with soft ligands and can make close Cu···Cu contacts, features that can promote uncommon bonding, reactivity and catalytic properties of multinuclear copper complexes. Bis(diphenylphosphanyl)methane (dppm), for example, has been reported on multiple occasions to be a diphosphine ligands that is able to lock two metal atoms together in close proximity (Yang et al., 2000; Liaw et al., 2005; Jin et al., 2009). Copper complexes of thiourea ligands such as 1-ethylthiourea (ettu), on the other hand have been of increasing interest due to the variety of their structures and their similarity to metallothioneines, i.e. they contain coordinated Cu—S moieties which play an important role in animals and plants. Herein, the
of a dinuclear copper(I) iodode complex containing both dppm and ettu is described.The molecular structure of the dinuclear title compound is shown in Fig. 1. Each CuI ion displays a distorted tetrahedral coordination geometry with internal angles in the range 97.00 (4)–119.56 (4)°. The dppm ligand and the bridging S atom of the ettu ligand force the two copper atoms into close proximity, leading to the formation of a close intramolecular Cu···Cu contact [3.3747 (17) Å]. The Cu—P distances vary from 2.2563 (10) to 2.2786 (11) Å, which are quite similar to those observed in related copper(I) complexes containing the dppm ligand (Yam et al., 2001; Zhou et al., 2001). The Cu—S bond lengths (Cu1—S1 = 2.3450 (11), Cu2—S1 = 2.3493 (11) Å) are shorter than that found in for example [Cu2(µ-HL1)2(µ-dppm)(η1-dppm)2] (H2L1 = 8-mercaptotheophylline), which are 2.392 (5)–2.410 (6) Å (Colacio et al., 1997). The terminal Cu—I bond distances (Cu1—I1 = 2.6694 (6) and Cu2—I2 = 2.6690 (5) Å), are in their typical ranges [see e.g. Nimthong et al., 2008; Pakawatchai et al., 2012]. The conformation of the dinuclear complex is such that the two dppm ligands are located on one side of the metal complex, while the two iodine atoms are pointed towards the other side of the complex. This conformation is stabilized by two intramolecular N—H···I hydrogen bonds between the ettu NH2 and NHEt moieties and the iodine atoms with N···H distances of 3.796 (4) (for N1···I2) and 3.563 (4) Å (for N2···I1), respectively (Table 1). In the crystal, the N and I atoms are also involved in intramolecular N—H···I hydrogen bonds to form dimers across an inversion center (symmetry code: -x, -y, -z + 1) (Table 1, Fig. 2). The dimers are in turn connected with each other and with the interstitial acetonitrile solvate molecules via a range of weaker C—H···I and C—H···S interactions (Table 1) and through a weak C(sp2)—H···π interaction [C14—H14···Cg1iv, with H14···Cg1iv = 3.38 (3) Å, C14···Cg1iv = 4.09 (3) Å and C14—H14···Cg1iv = 129.4 (4)°, Cg1 = C41—C42—C43—C44—C45—C46 ring, symmetry code: (iv) -x+1/2, y-1/2, -z+1] leading to the formation of a three-dimensional network, Fig. 3 and Table 1. One of the solvent acetonitrile molecules is disordered in a 1:1 ratio across a crystallographic inversion center.

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. |

Metal(I) complexes with mixed phosphine and sulfur donor ligands have attracted much attention in recent years because of various applications based on e.g. their luminescent properties (Safin et al., 2010) or antimicrobial activities (Isab et al., 2010). CuI ions functioning as Lewis acids tend to form covalent bonds with soft ligands and can make close Cu···Cu contacts, features that can promote uncommon bonding, reactivity and catalytic properties of multinuclear copper complexes. Bis(diphenylphosphanyl)methane (dppm), for example, has been reported on multiple occasions to be a diphosphine ligands that is able to lock two metal atoms together in close proximity (Yang et al., 2000; Liaw et al., 2005; Jin et al., 2009). Copper complexes of thiourea ligands such as 1-ethylthiourea (ettu), on the other hand have been of increasing interest due to the variety of their structures and their similarity to metallothioneines, i.e. they contain coordinated Cu—S moieties which play an important role in animals and plants. Herein, the crystal structure of a dinuclear copper(I) iodode complex containing both dppm and ettu is described.
The molecular structure of the dinuclear title compound is shown in Fig. 1. Each CuI ion displays a distorted tetrahedral coordination geometry with internal angles in the range 97.00 (4)–119.56 (4)°. The dppm ligand and the bridging S atom of the ettu ligand force the two copper atoms into close proximity, leading to the formation of a close intramolecular Cu···Cu contact [3.3747 (17) Å]. The Cu—P distances vary from 2.2563 (10) to 2.2786 (11) Å, which are quite similar to those observed in related copper(I) complexes containing the dppm ligand (Yam et al., 2001; Zhou et al., 2001). The Cu—S bond lengths (Cu1—S1 = 2.3450 (11), Cu2—S1 = 2.3493 (11) Å) are shorter than that found in for example [Cu2(µ-HL1)2(µ-dppm)(η1-dppm)2] (H2L1 = 8-mercaptotheophylline), which are 2.392 (5)–2.410 (6) Å (Colacio et al., 1997). The terminal Cu—I bond distances (Cu1—I1 = 2.6694 (6) and Cu2—I2 = 2.6690 (5) Å), are in their typical ranges [see e.g. Nimthong et al., 2008; Pakawatchai et al., 2012]. The conformation of the dinuclear complex is such that the two dppm ligands are located on one side of the metal complex, while the two iodine atoms are pointed towards the other side of the complex. This conformation is stabilized by two intramolecular N—H···I hydrogen bonds between the ettu NH2 and NHEt moieties and the iodine atoms with N···H distances of 3.796 (4) (for N1···I2) and 3.563 (4) Å (for N2···I1), respectively (Table 1). In the crystal, the N and I atoms are also involved in intramolecular N—H···I hydrogen bonds to form dimers across an inversion center (symmetry code: -x, -y, -z + 1) (Table 1, Fig. 2). The dimers are in turn connected with each other and with the interstitial acetonitrile solvate molecules via a range of weaker C—H···I and C—H···S interactions (Table 1) and through a weak C(sp2)—H···π interaction [C14—H14···Cg1iv, with H14···Cg1iv = 3.38 (3) Å, C14···Cg1iv = 4.09 (3) Å and C14—H14···Cg1iv = 129.4 (4)°, Cg1 = C41—C42—C43—C44—C45—C46 ring, symmetry code: (iv) -x+1/2, y-1/2, -z+1] leading to the formation of a three-dimensional network, Fig. 3 and Table 1. One of the solvent acetonitrile molecules is disordered in a 1:1 ratio across a crystallographic inversion center.
