Simultaneous Raman spectroscopy and inelastic
neutron scattering have been used to obtain structural information
about the isomeric metal-organic polymers trans-[{RuCp-
(PTA)2-μ-CN-1κC:2κ2N-RuCp(PTA)2}-μ-CoCl3]n·(DMSO)n (2), cis-
{[{RuCp(PTA)2-μ-CN-1κC:2κ2N-RuCp(PTA)2}-μ-CoCl3]}n·{[RuCp-
(PTA)2-μ-CN-1κC:2κ2N-RuCp(PTA)2]Cl}0.5n·(15H2O)n (3) and
{[{RuCp(PTA)2-μ-CN-1κC:2κ2N-RuCp(PTA)2}-μ-CoCl3]}n·{[RuCp-
(PTA)2-μ-CN-1κC:2κ2N-RuCp(PTA)2]Cl}0.5n (4) (PTA = 1,3,5-triaza-
7-phosphaadamantane). Despite the complexity of the compounds,
the combination of both techniques has been useful
to understand the conformation-dependent fingerprint of the
polymers and, at the same time, to obtain preliminary information
about how the water molecules are confined in the structural
channels of 3.
