Two novel copper(II) polynuclear complexes with deprotonated 4-iodopyrazole (Ipz) of composition [Cu3(µ3-OH)(µ-Ipz)3Cl2 · 2CH3CN]2 (1) and [Cu3(µ3-OH)(µ-Ipz)3Br2]n (2) have been synthesized and isolated in crystalline state. Crystal and molecular structure of both compounds has been studied by single crystal X-ray diffraction. The structure of complex 1 consists of dimerized 9-azametallacrown-3 fragments Cu3(µ3-OH)(µ-Ipz)3Cl2 · 2CH3CN connected between each other by chlorine anions. The dimeric molecules are united into polymeric chains with the help of hydrogen bonds between the hydrogen atoms of μ3-OH-group and the chlorine anions of the neighboring fragment. Complex 2 is crystallized as polymeric structure, consisting from the trinuclear fragments Cu3(µ3-OH)(µ-Ipz)3Br2 united by bridging bromine atoms. It is established that in the case of complex 1 the Cu(II) coordination number is complemented up to 5 on account of acetonitrile molecule, whereas in complex 2 the pentacoordinated geometric environment of copper(II) ions is formed by two bridging bromine anions belonging to the neighboring structure subunit.
