A new tetranuclear pyrophosphate-bridged Cu(II) complex with 4,4'-bipyridine and 1,10-phenanthroline [Cu-4(phen)(4)(bPY)(2)(P2O7)(2)]center dot 10H(2)O (1) has been hydrothermal synthesized and characterized by single-crystal X-ray analysis, element analysis, IR spectroscopy, TG analysis, and UV-vis spectra. Variable-temperature magnetic susceptibility measurements show the occurrence of antiferromagnetic interactions between the neighbor Cu(II) centers in 1. The analysis of the magnetic data in the whole temperature range allows the determination of the value of the intramolecular magnetic coupling (J = -13.16 cm(-1)).
