- Аннотация: The reaction of pyrrole-2,5-dicarbaldehyde (1) with o-phenylenediamine (2) ill anhydrous EtOH afforded a [1+1]-condensation product, viz., Schiffs base. The structure of the latter was established by NMR spectroscopy and X-ray diffraction analysis. The reaction of this product or a Mixture of 1 and 2 with Ni-9(mu(n)-OOCBut)(12)(HOOCBu1)(4)(mu(4)-OH)(3)(mu(3)-OH)(3) in MeCN in the presence of AcOH gave rise to all antiferromagnetic binuclear complex. According to the X-ray diffraction data, the macrocycle in the latter complex is a [2+2]-condensation product of compounds 1 and 2, mu(eff) ranging from 0.569 to 2.614 muB (2-301 K), -2J = 360 cm(-1). The Ni-2(OAc)(2) fragment is located in the central cavity of the macrocycle. The structures of the condensation products are discussed based on the results of DFT quantum-chemical calculations.
