“…Each tin is five-coordinate in a distorted trigonal-bipyramidal geometry (τ = 0.732) with the oxygen atoms occupying the axial positions (Supporting Information, Figure S4). The carboxylate and the uracil oxygen atom bind to tin in an analogous manner to what was observed for [{Sn(C 4 H 9 ) 3 (uracil-1-acetate)} n ] …”

The reaction of 3-(N1-uracyl)propanoic acid (LH) with (t-Bu 2 SnO) 3 in a 3:1 ratio afforded the hydroxidebridged dimer [t-Bu 2 Sn(μ-OH)L] 2 (1). A similar reaction involving bis(tri-n-butyltin)oxide, (n-Bu 3 Sn) 2 O, in a 2:1 ratio afforded the one-dimensional (1D) coordination polymer [(n-Bu 3 SnL)] n (2). Similarly, the reaction of LH with (MeOAr) 2 TeO in a 2:1 ratio afforded the mononuclear [(MeOAr) 2 TeL 2 ]•H 2 O (3). On the other hand, a similar reaction in a 1:1 ratio gave the dinuclear product [{(MeOAr) 2 TeL} 2 O]•C 2 H 5 OH•CH 3 OH• H 2 O (4). The reaction of complex 1 with CuCl 2 in a 1:1 ratio yielded [Cu(II)L 2 H 2 O] 2 •6H 2 O (5). All the complexes show an extensive supramolecular organization in the solid state as a result of several intermolecular interactions. The role of uracil substituents in determining the final course of the supramolecular assembly is discussed. A tetrameric uracil supramolecular motif is formed in the crystal structure of complex 1 as a result of C− H•••O interactions. Uracil−water interactions involving only C−H•••O interactions have been observed in complex 5.

“…Such binding modes involving an additional hetero atom, though uncommon, are known. 51,52 It is noteworthy to mention here that in the current instance, participation of the (O2) carbonyl oxygen atom of uracil is observed in contrast participation of (O4) in [{SnĲC 4 H 9 ) 3 (uracil-1-acetate)} n ] 53 and [{Sn(C 4 H 9 ) 3 (uracil-1propionate)} n ]. 34 Both the tin centres of complex 4 are fivecoordinate in a distorted trigonal bipyramidal geometry with the oxygen atoms occupying the axial positions.…”

The reaction of L1H {L1H = 3-(N9-guaninyl)propionic acid} with Me 3 SnCl or (n-Bu 3 Sn) 2 O afforded the 1D coordination polymers, [Me 3 Sn(L1)] n (1) and [n-Bu 3 Sn(L1)] n (2) respectively. A reaction between L2H {L2H = 3-(N7-guaninyl)propionic acid} with Me 3 SnCl also afforded a 1D coordination polymer, [Me 3 Sn(L2)] n (3). A similar reaction between L3H [uracil-6-carboxylic acid] with (Ph 3 Sn) 2 O in a 2 : 1 ratio afforded a dimer [(n-Bu 3 SnL3) 2 •H 2 O] (4). A mononuclear compound [Me 3 Sn(L4)•H 2 O] (5) was obtained in a 1 : 1 reaction of 3-{N9-(2-aminopurinyl)}propanoic acid (L4H) with Me 3 SnCl. Complexes 1-5 show rich supramolecular structures in the solid state as a result of several intermolecular interactions. Thus, in the one-dimensional coordination polymer 3, triple hydrogen bonding (GG), between inter-chain guanine units has been observed. Similarly a homo orotatequartet has been observed in 4 as a result of intermolecular interactions.
