Catena-Poly[[silver(I)-?-1,2-bis-(4,4-dimethyl-4,5-dihydro-1,3-oxazol-2-yl)ethane-?(2)N:N'] perchlorate hemihydrate].

ABSTRACT: In the title coordination polymer, {[Ag(C(12)H(20)N(2)O(2))]ClO(4)·0.5H(2)O}(n), the Ag(I) cation is coordinated by two N atoms from two 1,2-bis-(4,4-dimethyl-4,5-dihydro-1,3-oxazol-2-yl)ethane (L) ligands in a nearly linear geometry [N-Ag-N = 171.07?(8)°]. The L ligand bridges adjacent Ag(+) cations, forming a polymeric chain running along the c axis. The lattice water mol-ecule is situated on a twofold rotation axis, and links to the perchlorate anion via an O-H?O hydrogen bond. The long Ag?O separation of 3.200?(4)?Å indicates a weak inter-action between the perchlorate anion and the Ag(I) cation. Weak C-H?O hydrogen bonding occurs between the chain and the lattice water mol-ecule and between the chain and perchlorate anions. Both five-membered rings of the L ligand display envelope conformations; in one five-membered ring, the flap C atom is disordered on opposite sides of the ring with occupancies of 0.65 and 0.35.
