A growing family: New structures of coordination polymers containing adamantane-shaped phosphorus–nitrogen cage ligands

Two new structurally characterized coordination polymers containing the P4(NR)6 ligand system are described. A convenient one-pot synthesis of P4(NR)6 (R = benzyl) via reaction of lithiated primary amine with phosphorus trichloride demonstrates an expanded scope for the preparation of this adamantane-type structure. Reactions of P4(NR)6 (R = Et, Bn) with cuprous iodide yield different products due to the differences in steric demands of the ligands.
