“…Linking of the previously discussed P/N adamantane-type structures [P4(NR)6] (936-938, R = Me, Et, Bn, Figure 21) can be achieved by the addition CuI to form one dimensional chains of [{P4(NR)6}CuI]n (R = Me, Et) with µ bridging CuI moieties or [{P4(NMe)6}(CuI)2(MeCN)2]n comprising linking CuI and MeCN four membered rings. [81,533] Similiarly, reactions of [P4(NMe)6] with CuCl lead to a three dimensional network [{P4(NMe)6}2(CuCl)3(MeCN)2] (939) or a ladder like one dimensional polymer [{P4(NMe)6}(CuCl)2]n (940) depending on the cluster to CuCl ratio. [526] Ligands on [(PNSiMe3)4(NMe)6] can be exchanged for TiCl3 or p-n BuPhPCl2, which polymerize to form extended networks that could not yet be structurally characterized (941-942).…”
