Covalent self-assembly of the specific RSSR isomer of 14-membered tetrakisphosphine†
Abstract
The first representative of the specific RSSR isomer of 14-membered tetrakisphosphine has been obtained instead of the RRRR/SSSS isomer predicted according to the empirical rule formulated recently. The geometry of the obtained 14-P4N2 is preorganized for the dicopper complex formation with the unique coordination mode in the row of P4N2 corands.
