The title compound, [Cd(C13H14N2)4(H2O)2](NO3)2·2H2O, has been prepared from the self-assembly reaction of oligoaniline dadpm (dadpm is diaminodiphenylmethane) and Cd(NO3)2 in MeOH/H2O. The CdII mononuclear complex cation has a center of symmetry, and dadpm acts as a monodentate ligand.

A mixture of Cd(NO3)2 (0.08 g, 0.25 mmol) and dadpm (0.10 g, 0.50 mmol) in
water/methanol (10/20) was stirred for 3 h. The colorless solution was allowed
to evaporate slowly for a week, after which time, colorless crystals of (I)
were obtained.
The positions of the H atoms were genetared geometrically (C—H bond fixed at
0.96 Å), assigned isotropic displacement parameters and allowed to ride on
their respective parent C atoms, and the positions of the water H atoms were
refined with isotropic displacement parameters before the final cycle of
least-squares refinement. There are short intermolecular H···H contacts;
HOB···H01i = 2.06 Å, H01···H4Bii = 2.09 Å and H02···H2Biii = 1.99 Å (see Table 2 for symmetry codes). However, the assumed H-atom positions
are reasonable based on the following angles, O1···H01i—O101i = 63.9°,
O101···H4Bii—N4ii = 89.4° and O101···H2Biii—N2iii = 95.9°.

Special details top
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. |

In recent decades, there has been great interest in the study of metal–organic supramolecular frameworks owing to their intriguing structral diversity and potential application in catalysis, separation and molecular recognization (Piguet et al., 1997; Yaghi et al., 1998; Swiegers et al., 2000). In the construction of one-, two- and three-dimensional frameworks, the rational design and selection of ligands are crucial for the formation of metal–organic coordination frameworks. For example, many rigid ligands, such as 4,4-bipyridine or polycarboxylic acids, and flexible ligands, such as bipyridine derivatives with spacers, have been extensively employed in the formation of supramolecular architectures (Yang et al., 2001; Wang et al., 2001; Horikoshi et al., 2001). The displacement of oligopyridine by oligoaniline should result in new structural motifs and new topologies, but oligoaniline ligands are seldom employed (Zhang et al., 1999). In this paper, we report the crystal structure of [Cd(dadpm)4(H2O)2](NO3)2·2H2O, (I), obtained from the self-assembly of dadpm and Cd(NO3)2.
Compound (I) is a mononuclear CdII complex and dadpm serves as a monodentate ligand (Fig. 1). The Cd atom is coordinated by N atoms from four different dadpm ligands and O atoms from two water molecules, forming a distorted octahedral coordination fashion of CdN4O2. The Cd—N and Cd—O bond distances are 2.363 (3)–2.405 (3) and 2.295 (3) Å, respectively (Table 1).
