Vs. Reddy et al., ORGANOMETALLICS OF DIPHOSPHAZANES .10. DINUCLEAR GROUP-6 METAL-CARBONYL-COMPLEXES BRIDGED BY A CYCLODIPHOSPHAZANE IN ITS CIS OR TRANS FORM, Journal of the Chemical Society. Dalton transactions, (18), 1994, pp. 2661-2667
Mononuclear Group 6 metal tetracarbonyl complexes containing a cyclodi
phosphazane ligand, [PhNP(OC(6)H(4)Me-p)](2) (L), have been used as sy
nthons to prepare homo- and hetero-bimetallic complexes in which the c
yclodiphosphazane bridges the two metal centres in its cis or trans is
omeric forms. The dimolybdenum complex [Mo-2(eta(5)-C5H5)(2)(CO)(4)(mu
-L)] has also been synthesized. The trends in P-31 NMR chemical shifts
and the structural features as revealed by X-ray crystallography are
discussed.
