Abstract
[La(NO3)3(OH2)2(OHMe)(bipy)·15-crown-5 is monoclinic,P2t/n, witha=11.239(6),b=19.302(7),c=14.458(8) Å, β=92.47(5)°, andD calc=1.63 g cm−3 forZ=4. In the complex, two nitrogen atoms (from bipy) and nine oxygen atoms (six from three bidentate nitrate anions, two from water molecules, and one from a methanol molecule) coordinate to the La(III) ion forming a coordination polyhedron which approximates a skewed trigonal prism with an interpenetrating pentagon. The coordinated methanol and water molecules donate hydrogen bonds to the oxygen atoms of the crown ether forming polymeric hydrogen bonded chains which propagate along theac diagonal in the unit cell.
