In (I), these two types of metals are bridged by benzene-1,2,4,5-tetracarboxylic acid (H4BTA). Although no crystallographic void was detected in (I), it can adsorb N2 gas to a certain extent.

In this research, compound (I) was prepared by dissovling Cu(NO3)2·2(H2O) (0.2 mmol, 48.0 mg), CaCl2 (0.2 mmol, 23 mg) and H4BTA acid (0.2 mmol, 51.0 mg) in 10 mL of water.

Furthermore, the diamagnetic analogue of the desired complex has to be isomorphic. Since mononuclear cobalt(II) complexes can be a single-ion magnet,2,3 the preparation of a zinc(II) analogue is important. On the other hand, we recently reported that the bis[2-(1,4,5,6-tetrahydropyrimidin-2-yl)phenolato]cobalt(II) complex exhibits magnetic slow relaxation, even in the absence of an external magnetic field.3 It is suggested that the origin of the slow relaxation is to be intermolecular magnetic interactions induced by hydrogenbonding interactions. To investigate the effect of intermolecular interactions, we focused on the synthesis, crystal structure and hydrogen-bonded supramolecular structure of the zinc(II) analogue, bis[2-(1,4,5,6-tetrahydropyrimidin-2-yl)phenolato]zinc(II) (Fig. 1). The unsymmetrical bidentate ligand precursor, 2-(1,4,5,6tetrahydropyrimidin-2-yl)phenol (H2thp), was synthesized by a reported procedure.4 Although previously reported [Co(Hthp)2] was synthesized from the Co(BF4)2·6H2O, preparation of [Zn(Hthp)2] from the BF4 salt resulted in the formation of colorless microcrystals. Alternatively, colorless single crystals of [Zn(Hthp)2] were obtained by a reaction of ZnCl2, H2thp and KOtBu in a 1:2:2 ratio in ethanol. Yield: 34.1 mg (40%). Crystal data are included in Table 1.

In this paper, we report on the crystal structure of 1 together with the reactivity toward dioxygen. The tridentate ligand L·H2O was synthesized according to a literature method.7 The diiron(II) complex with L was prepared under a N2 atmosphere. A mixture of Fe(CF3SO3)2·2CH3CN (0.436 g, 1.0 mmol) and L·H2O (0.456 g, 1.0 mmol) in dryTHF/CH2Cl2 (1:1, 20 mL) was added a THF solution (3 mL) containing H2O (18 μL, 1.0 mmol) and triethylamine (138 μL, 1.0 mmol) to give a yellow-green solution.

Single crystals of [Fe2(OH)2(L)2](ClO4)2 (1) suitable for X-ray crystallography were obtained by slow diffusion of diethyl ether onto a dry-CH2Cl2/MeCN (1:1) solution of a yellow-green powder containing (n-Bu)4NClO4. X-ray diffraction measurements were made on a Rigaku CCD Mercury diffractometer with graphite-monochromated Mo Kα radiation at 123 K. The structure was solved by a direct method (SHELXS 97)9 and expanded using a Fourier technique. The structure was refined by a full-matrix least-squares method by using a SHELXL 201410 (Yadokari-XG).11 All non-hydrogen atoms were refined with anisotropic displacement parameters. The μ-hydroxo hydrogen atoms were refined using distance restraints with Uiso constrained to 1.2-times the Ueq of the parent oxygen atoms. Other hydrogen atoms were included using a riding model. The crystal data are summarized in Table 1. X-ray crystallography of 1 reveals that the asymmetric unit contains a half of the complex cation [Fe2(OH)2(L)2] and a perchlorate anion.
