✦ Synopsis

The dlfference between the metal-metal 6 and TT orbItal lonlzation energws for the complexes M~(OZCCF&, M2(02CCH3)4, M2(CaHsf.+_ and Mz(hlHP)1, (where M = Cr or MO and H{MHP)= 6-methyl-2-hydrouypyrtdme) mcreases, wtthm each series. as the metal-metal bond length decreases. The vanahon m the metal-metal bond length 1s more me&ed for the c$+ compfe=s where the mawnttude of the metal-metal tonrzatton energies decrease as the Cr-Cr separation con--C% thus SWgestmg that the coulombtc repuklon between these metal atoms IS a prime factor which determmes ther separation m these complexes
