Molecular and crystal structure of 2,4,4,6,6,8,8‐heptamethyl‐2‐[3‐{[2,4,4,6,6‐pentakis(dimethylamino)‐2,2,4,4,6,6‐hexa‐hydro‐1,3,5,2,4,6‐triazatriphosphorine‐2‐yl]amino}propyl]‐cyclotetrasiloxane

Abstract

Molecular and crystal structure of the title compound has been determined. The (PN)3 and (SiO)4 rings form the dihedral angle of 100.1° and with the HNCH2CH2CH2 plane the angles of 110.2° and 75.7° respectively. The molecular packing is built of alternating layers of (PN)3 and (SiO)4 beterocycles.

Synthesis and Characterization of Aminoorganosiloxane-Bearing Polyphosphazenes: New Properties by the Elimination of Hydrogen Bonding

“…The uses of such polymers in membranes and in hydrophobic surfaces are subjects of additional interest. Several research groups have explored the possibility that hybrid systems of this type may be accessible. − However, until recently, relatively few successful macromolecular syntheses have been described. − …”

“…Several research groups have explored the possibility that hybrid systems of this type may be accessible. [6][7][8][9][10][11][12][13][14][15] However, until recently, relatively few successful macromolecular syntheses have been described. [16][17][18][19][20][21][22][23][24] An approach being followed in our program is to link organosilicon side groups to a high polymeric phosphazene chain.…”
