摘要：

Reaction of copper(II) chloride dihydrate in methanol with deprotonated 3,5-diisopropylpyrazole-1-methanol (dippmOH) led to the tetranuclear copper(II) complex [(dippmO)CuCl](4) (1). The crystal structure of 1 indicates that two copper(II) ions connect via the oxygen atoms of dippmO(-) ligands each other in which two dimeric units are formed. Furthermore, one of the coordinated oxygen atoms in a dimer is bonded to an adjacent copper(II) ion positioned other dimer, which gives rise to a stepped tetranuclear structure. 1 shows strong antiferromagnetic interactions through the oxo groups within the dimeric units (J(1) = 239 cm(-1)) and weak antiferromagnetic couplings between the dimers (J(2) = 15 cm(-1)).
