| description | Complexes {[(PTA)2CpRu-μ-CN-1κC:2κ2N-RuCp-
(PTA)2-ZnCl3]}·2DMSO (13) {[ZnCl2(H2O)]-(PTA-1κP:2κ2N)-

(CF3SO3)2 (20), [RuCp(HdmoPTA)(HPTA)(PPh3)](CF3SO3)3
(21), and [RuCp(dmoPTA)(PPh3)(PTA)](CF3SO3) (22) were
obtained and characterized, and their crystal structure together with
that of the previously published complex 18 is reported. The
behavior of the 1,3,5-triaza-7-phosphatricyclo[3.3.1.13,7]decane
(PTA) and 3,7-dimethyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane
(dmoPTA) ligands against protonation and κN-coordination is
discussed, on the basis of 15N nuclear magnetic resonance data
collected on 22 different compounds, including PTA (1), HdmoPTA
(7H), and some common derivatives as free ligands (2−6 and 8),
along with mono- and polymetallic complexes containing PTA and/or
HdmoPTA (9−22). 15N detection via 1H−15N heteronuclear
multiple bond correlation allowed the construction of a small library
of 15N chemical shifts that shed light on important features
regarding κN-coordination in PTA and its derivatives. |
