Popis: Three bridged complexes of the form [(tmpa)Cr(O)(RCO 2 )Cr(tmpa)] 3+ (R=H, CH 3 , C 6 H 5 ; tmpa=tris(2-pyridylmethyl)amine) have been prepared and characterized through measurements of electronic and infrared spectra, ionization constants of conjugate hydroxy-bridged acids, magnetic susceptibility temperature dependences, and cyclic voltammograms. A perchlorate salt of the methyl derivative, [(tmpa)Cr(O)(CH 3 CO 2 )Cr(tmpa)](ClO 4 ) 3 (Cr 2 Cl 3 O 15 N 8 C 38 H 39 O.7H 2 O), crystallizes in the monoclinc systems space group P2 1 /c
