The synthesis and characterization of nine trinuclear, mixed metalcomplexes of the type[LV{
-(PhO)2PO2}3]2M,where the vanadium is in the 3+ oxidation state, L =hydrotris(pyrazolyl)borate, and M = Ba(II)(1), Ca(II) (2),Mg(II) (3), Mn(II) (4), Co(II)(5), Ni(II) (6), Fe(II) (7),2 Na(I) (8), Al(III) (9), andLa(III) (10), are described.X-ray crystal structural analysis of 1, 3,and 4 gave the following parameters: 1,C92H84B2N12O24P6Cl4BaV2,C2/c, a = 26.730(5) Å,b = 15.521(3) Å, c = 27.648(6) Å,

c, a = 18.670(3) Å,b = 18.671(3) Å, c = 61.114(12)Å, Z = 6. Magneticmeasurements indicate that compounds containing an integral spincentral ion display moderate antiferromagneticcoupling while those with half-integral spins give more complexbehavior.
