The crystal structure of bis{1,3-bis[bis(pyridin-2-ylmethyl)amino]propan-2-olato-dizinc(II)}orthophosphate tris(perchlorate) octahydrate, [(Phos-tag)2-PO43−][ClO4−]3·8H2O was determined by the single-crystal X-ray diffraction method at 93.15 K. The titled complex crystallized in the monoclinic space group C2/c and Z = 4 with a = 16.8423(2), b = 21.3554(2), c = 19.9942(2)Å, β = 106.8690(10)°, and V = 6881.95(13)Å3. The R1 [I > 2σ(I)] and wR2 (all data) values were 0.0447 and 0.1142, respectively, for all 6253 independent reflections. In the crystal structure, each zinc(II) ion is coordinated with two pyridyl amines, a tertiary amine, an alkoxide oxygen, and a phosphate oxygen to form a trigonal bipyramidal geometry. The orthophosphate trianion connects two dinuclear zinc(II) complex (Phos-tag) in a μ4–η4 bridge mode.
