N. Feeder et al., Synthesis and structure of [Sn-9(Ndmp)(7)(HNdmp)(2)O-2], containing a bidentate double-cubane oxo fragment (H(2)Ndmp=2-amino-4,6-dimethoxypyrimidine, CHEM COMMUN, (11), 2001, pp. 1010-1011
The reaction of Sn(NMe2)(2) with H(2)Ndmp (H(2)Ndmp = 2-amino-4,6-dimethoxy
pyrimidine) and H2O (ca. 4:4:1 equivalents, respectively) gives the cage co
mplex [Sn-9(Ndmp)(7)(HNdmp)(2)O-2] 1, containing an oxo double-cubane fragm
ent [Sn-7(Ndmp)(6)O-2] coordinated to a neutral (HNdmpSn)(2)(mu -Ndmp) unit
; 1 is the largest imido Sn(ii) complex so far characterised.
