    Abstract

    One-dimensional (1D) and three-dimensional (3D) coordination polymers comprising triangular [Pt 3 (NO 2 ) 63 -O)] 2− ([Pt3] 2− ) units were prepared from K 2 [Pt3]·3H 2 O (1), also known as Vèzes' red salt. The reaction between 1 and excess 18-crown-6 ether afforded the 1D coordination polymer [K(18-crown-6)] 2 [Pt3] (2), whereas the reaction between 1, excess 18-crown-6 ether, and AgPF 6 afforded the 1D coordination polymer [Ag(18-crown-6)] 2 [Pt3]·(CH 3 ) 2 CO (3). However, the reaction between 1 and equimolar amounts of 18-crown-6 and AgPF 6 afforded the 3D coordination polymer [Ag 2 (18-crown-6)][Pt3]·(CH 3 ) 2 CO (4). Furthermore, the 3D coordination polymer [Ag 2 Pt 33 -O)(NO 2 ) 6 ((CH 3 ) 2 CO) 2 ]·(CH 3 ) 2 CO (5) containing three Pt 2+ → Ag + dative bonds was obtained by the reaction of 1, Bu 4 NPF 6 , and AgPF 6 . The N 2 , O 2 , and CO 2 gas absorption isotherms of 1-5 were obtained, revealing that the dry crystals of 4 exhibit a selective CO 2 absorption ability.
