✦ Synopsis

phases of the main group metals remain largely unex-The first Sn(II)-organophosphonate solid phases have been plored. Consequently, while molecular clusters of the tinprepared and structurally characterized by single crystal X-ray organophosphonate system have been described (12) as diffraction. The one-dimensional species [Sn(HO 3 PCH 2 PO 3 H)] well as Sn(IV)/phenylphosphonates of poor crystallinity ؒH 2 O (1) was prepared conventionally from a mixture of SnCl 2 , assumed to possess the Ͱ-layered structure (13), no struc-CH 2 (PO 3 H 2 ) 2 , and H 2 O in the mole ratio 1:2.9:8.17 kept at turally characterized solid phases have been reported to 4؇C for 12 h. The three-dimensional phase [Sn 2 ͕O 3 PC(OH) date, nor has the influence of lone pair electrons on struc-(CH 3 )PO 3 ͖] (2) was prepared hydrothermally from a mixture tural characteristics been evaluated in the specific case of SnCl 2 , CH 3 C(OH)(PO 3 H) 2 , 1,4 diaminopropane ؒ HCl, and of Sn(II)-organophosphonates ( 14). In this article, H 2 O in the mole ratio 1:3.87:1.9:2215 with pH adjusted to 3.5 we report the preparations and structures of two by addition of (CH 3 ) 4 NOH, heated at 150؇C for 135.5 h.
