 abstract = {The trinuclear copper complex, [Cu3(\textgreek{m}3-OH)(CTMB)3(NO3)2(CH3CN)2]·5CH3CN·H2O (1) {CTMB = cyclohexotriazole-3-(4-methoxybenzamide)}, has been prepared by mixing Cu(NO3)2·2.5H2O and CHMBH {CHMBH = N,N′-cyclohexane-1,2-diylidene- bis(4-methoxybenzoylhydrazide)} in acetonitrile under ambient conditions. Compound 1 was characterized by IR and UV--visible spectroscopies as well as elemental analyses. X-ray crystallography shows that the cluster contains a {Cu3(μ3- OH)} core supported by three triazole-based Schiff base ligands. Each Cu is bound to the 2-N of one triazole ring and the 1-N of another. However, the coordination sphere of each Cu is different, one is five-coordinate and the other two are sixcoordinate and bridged by a NO3 group. The six-coordinate sites are different, one has a terminal NO3 and the other a MeCN ligand. Magnetic measurements revealed the presence of isotropic and antisymmetric exchange between the copper(II) centers. The data were analyzed using the Hamiltonian containing isotropic exchange for an isosceles triangle together with antisymmetric exchange: H = --J1(S1S2 + S2S3)$-$J2S1S3 + G[S1 $\times$ S2 + S2 $\times$ S3 + S3 $\times$ S1]. Compound 1 exhibits strong antiferromagnetic coupling with J1 = $-$180 and J2 = $-$118 cm$-$1 and antisymmetric exchange with Gz = 15 cm$-$1. Stopped flow spectrophotometric studies show that the formation of 1 occurs in three distinct phases and the kinetics of each phase  1 exhibits strong
