A mixture of cadmium acetate (0.5 mmol), 3,3',4,4'-benzophenone tetracarboxylic acid (0.5 mmol) and 1,10-phenanthroline (0.5 mmol) in 20 ml solution of water and ethanol (1:1) was sealed in an 30 ml Teflon-lined stainless autoclave, and kept at 423 K for 2 days. Colorless block-shaped crystals were obtained in 16% yield after slowly cooling to room temperature. Anal. Calc. for C65H42Cd2N8O11: C 58.38, H 3.14, N 8.38, Cd 16.83%; Found: C 58.31, H 3.11, N 8.29, Cd 16.76%.
C-bound H atoms were generated geometrically (C—H = 0.93 Å) and refined as riding, with Uiso(H)= 1.2Ueq(C). H atoms of the water molecule were located in a difference map and were refined with distance restraints of H···H = 1.38 (2) and O–H = 0.82 (2) Å, and with a fixed Uiso(H) of 0.80 Å2. The highest peak and deepest hole in the difference Fourier map are located 0.92 and 0.65 Å, respectively, from atoms Cd1 and O6.
Hybrid organic-inorganic materials occupy a prominent position by virtue of their applications to catalysis, optical materials, membranes, and sorption (Ngo et al., 2004; Evans et al., 2001; Vioux et al., 2004; Sanchez et al., 2003; Evans & Lin, 2001; Jannasch, 2003; Javaid et al., 2001; Honma et al., 2001; Sudik et al., 2005; Rowsell et al., 2004; Kitaura et al., 2002). The design of organic-inorganic hybrid materials is conceived of the metal, metal cluster, or metal oxide substructure as a node from which rigid or flexible multitopic organic ligands radiate to act as tethers to adjacent nodes in the bottom-up construction of complex extended architectures. While a variety of organic molecules have been investigated as potential tethers, materials incorporating multitopic carboxylates and pyridine ligands have witnessed the most significant development. However, ligands offering alternative tether lengths, different charge-balance requirements, and orientations of donor groups may afford advantages in the design of materials. Herein, We report the structure of the new title complex, (I). The cadmium cation is hexa-coordinated by two carboxylate oxygen atoms from two 3,3',4,4'-benzophenone tetracarboxylate and four nitrogen atoms from two 1,10-phenanthroline, showing a slightly distorted octahedral geometry (Fig. 1). Each two Cd atoms form one circle via two half of 3,3',4,4'-benzophenone tetracarboxylate, which are further linked to form chains (Fig. 2). The Cd—N and Cd—O bond lengths are in the range of 2.392 (4)–2.524 (4) and 2.255 (3)–2.275 (4) Å, respectively.

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. |

Hybrid organic-inorganic materials occupy a prominent position by virtue of their applications to catalysis, optical materials, membranes, and sorption (Ngo et al., 2004; Evans et al., 2001; Vioux et al., 2004; Sanchez et al., 2003; Evans & Lin, 2001; Jannasch, 2003; Javaid et al., 2001; Honma et al., 2001; Sudik et al., 2005; Rowsell et al., 2004; Kitaura et al., 2002). The design of organic-inorganic hybrid materials is conceived of the metal, metal cluster, or metal oxide substructure as a node from which rigid or flexible multitopic organic ligands radiate to act as tethers to adjacent nodes in the bottom-up construction of complex extended architectures. While a variety of organic molecules have been investigated as potential tethers, materials incorporating multitopic carboxylates and pyridine ligands have witnessed the most significant development. However, ligands offering alternative tether lengths, different charge-balance requirements, and orientations of donor groups may afford advantages in the design of materials. Herein, We report the structure of the new title complex, (I). The cadmium cation is hexa-coordinated by two carboxylate oxygen atoms from two 3,3',4,4'-benzophenone tetracarboxylate and four nitrogen atoms from two 1,10-phenanthroline, showing a slightly distorted octahedral geometry (Fig. 1). Each two Cd atoms form one circle via two half of 3,3',4,4'-benzophenone tetracarboxylate, which are further linked to form chains (Fig. 2). The Cd—N and Cd—O bond lengths are in the range of 2.392 (4)–2.524 (4) and 2.255 (3)–2.275 (4) Å, respectively.
