The title complex, [Na(C18H22O5)(H2O)]2[Co(NCS)4], consists of two aqua(2,3-naphtho-15-crown-5)sodium complex cations and one [Co(NCS)4]2− complex anion, which has crystallographic symmetry. In the anion, the CoII centre is coordinated by the N atoms of four NCS− ligands in a distorted tetrahedral geometry. In the complex cations, the NaI centre is coordinated by five O atoms of the 2,3-naphtho-15-crown-5 ligand and one water O atom. The complex molecules form a two-dimensional network via weak O—H⋯S interactions between adjacent cations and anions

The title complex was prepared by adding 10 ml of an aqueous mixture of CoCl2 (0.032 g, 0.25 mmol) and NaSCN (0.81 g, 10 mmol) to a solution of 2,3-naphtho-15-crown-5 (0.16 g, 0.5 mmol) in 10 ml dichloromethane. The reaction mixture was stirred for 2 hrs at room temperature and filtered. The precipite was dissolved in the CH3CN, and the crystal was obtained a week later. m.p.: 470–472. Anal.

The C—H H atoms were positioned with idealized geometry and were refined as isotropic with Uiso(H) = 1.2 Ueq(C, O) for all H atoms using a riding model with C—H = 0.93 Å for aromatic H, and C—H = 0.97 Å for CH2. The S2 atom was refined using an approximately isotropic model (ISOR in SHELXL).
Due to the unusual coordination numbers and arrangements with various metal ions, π···π interactions (Dou et al., 2004; Gao et al., 2005). In order to study the weak interactions of the naphtho crown ether, we have synthesized the title complex by the reaction of naphtho-15-crown-5 with CoCl2 and NaSCN. The title complex, [Na(N15C5)H2O]2[Co(NCS)4] is made up of two [Na(N15C5)H2O]+ complex cations and one [Co(NCS)4]2- complex anion. In the complex anion, the Co is coordinated by four N atoms of the NCS ligands and exhibits a distorted tetrahedral geometry. The average Co—N bond length is 1.945 (4) Å, which is consistent with that of [K(18C6)]2[Co(SCN)4](1.94 Å) (Fan et al., 1985). In the complex cation, the Na is coordinated by five O atoms of the crown ether and one O atom of the H2O, The Na—O(crown ether) distances are in the range 2.329 (3) to 2.361 (3) Å), average 2.344 (3) Å, which is shorter than that of [Na(N15C5)][Pd(SCN)4] (Dou et al., 2004). The Na—O(H2O) bond length is 2.278 (3) Å, which is comparable to that of [{Na(18C6)}2(H2O)][Ni(i-mnt)2] (Yu et al., 2005). For the neighboring complex cations and the complex anions, the distances of O(6)···S(2) and O(6)—S(1) are 3.46 (3) Å and 3.39 (4) Å respectively, which are shorter than those in the complex {[(Me3Sn)(µ-OH)][Me2Sn(µ3-SCH2CO2)]}n (Zhang et al., 2006), indicating that there are O—H···S weak interactions between the neighboring complex cations and complex anions. The title complex is assembled into two-dimensional network by virtue of O—H···S weak interactions.
have attracted much attention (Pedersen, 1967; Zhang et al., 1996). In particular, the naphtho play an important role in crystal engineering of supramolecular interactions, such asFor crown ether complexes, see: Pedersen (1967); Zhang et al. (1996). For π···π interactions of the naphtho crown ether, see: Gao et al. (2005). For structural information on compounds with similar features, see Fan et al. (1985); Dou et al. (2004); Yu et al.

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. |

Due to the unusual coordination numbers and arrangements with various metal ions, crown ethers have attracted much attention (Pedersen, 1967; Zhang et al., 1996). In particular, the naphtho crown ethers play an important role in crystal engineering of supramolecular interactions, such as π···π interactions (Dou et al., 2004; Gao et al., 2005). In order to study the weak interactions of the naphtho crown ether, we have synthesized the title complex by the reaction of naphtho-15-crown-5 with CoCl2 and NaSCN. The title complex, [Na(N15C5)H2O]2[Co(NCS)4] is made up of two [Na(N15C5)H2O]+ complex cations and one [Co(NCS)4]2- complex anion. In the complex anion, the Co is coordinated by four N atoms of the NCS ligands and exhibits a distorted tetrahedral geometry. The average Co—N bond length is 1.945 (4) Å, which is consistent with that of [K(18C6)]2[Co(SCN)4](1.94 Å) (Fan et al., 1985). In the complex cation, the Na is coordinated by five O atoms of the crown ether and one O atom of the H2O, The Na—O(crown ether) distances are in the range 2.329 (3) to 2.361 (3) Å), average 2.344 (3) Å, which is shorter than that of [Na(N15C5)][Pd(SCN)4] (Dou et al., 2004). The Na—O(H2O) bond length is 2.278 (3) Å, which is comparable to that of [{Na(18C6)}2(H2O)][Ni(i-mnt)2] (Yu et al., 2005). For the neighboring complex cations and the complex anions, the distances of O(6)···S(2) and O(6)—S(1) are 3.46 (3) Å and 3.39 (4) Å respectively, which are shorter than those in the complex {[(Me3Sn)(µ-OH)][Me2Sn(µ3-SCH2CO2)]}n (Zhang et al., 2006), indicating that there are O—H···S weak interactions between the neighboring complex cations and complex anions. The title complex is assembled into two-dimensional network by virtue of O—H···S weak interactions.
