One-dimensional chain structures

Interesting examples of simple substituted heterometallic species are [(thf)M p-N(SiMe3)2 2M (th 2] (M/M = Li/Na, Li/K and Na/K) which were obtained from solutions of 1 1 mixtures of the metal salts.The unsolvated ( LiXtSiMe J , K- lSiXleO, ), has a polymeric, one-dimensional chain structure formed by alternating lithium and potassium centres bridged through the hexamethyldisilazides (Li—N= 1.935(1) A and K—N = 2.86(1) A) with linear coordination at K and almost linear coordination (N-Li= 176.4(3)°) atLi. ... [Pg.18]

Nd3(H20)i7(a2-P2Wi706i)] displays a one-dimensional chain structure built up of bisupporting anions [ Nd(H20)7 2 Nd(H20)3(a2-P2Wi706i) 2] and additional neodymium linkers [36], The structure of the bisupporting anions have similar stractures to the above mentioned [ Nd(H20)7 2 Nd(H20)3(a2-P2Wi706i) 2] cluster. [Pg.215]

Nd2(H20)i4 Na(H20)P5W3oOiio ] shows a one-dimensional chain structure built from Preyssler anions [Na(H20)P5W3oOno] " linked by neodymium cations. In the complex, the adjacent [Na(H20)P5W3oOno] clusters are linked to each other about a center of symmetry... [Pg.216]

Mo36Oi08(NO)4(MoO)2La2(H2O)28] possesses of a one-dimensional chain structure, in which the Mo36(NO)4 units are linked to each other by two parallel lanthanum atoms [74]. [Pg.216]

Crown thioether can not only form a one-dimensional chain structure, it can also form two-dimensional sheet frameworks (225). The crown thioether ligand (OH)2[16]aneS4 (L100) reacted respectively with silver nitrate and silver acetate, giving two polymeric silver(I) com-... [Pg.278]

A number of transition-metal coordination polymers have also been reported that involve CTV-type ligands with N-donor functionality. One-dimensional chain structures and 2D networks predominate and a striking feature is that the host-guest behavior that is observed in the simple clathrate complexes of the host ligands can also be observed within coordination polymers. For example, the hand-shake motif is observed in ID chain structures, for example, in... [Pg.885]
