Abstract:
Dichloro[2,6-diacetylpyridine bis(picolinoylhydrazonato)]
tin(IV) monohydrate, [Sn(C21-H17N7O2)Cl2].H2O, Mr= 607.02, monoclinic, P21/c,
a = 8.485 (5), b = 14.476 (6), c = 19.533 (12) Å,
β= 95.67 (8)°,V= 2387 (2)/Å3,Z= 4, Dx=
1.689g cm-3, Dmnot measured, λ(CuKa)=1.54178Å, μ=lll.60cm-1,F(000)=1208,T=
298 K, finalR=0.0604 for 1066 observed reflections.
The structure consists of discrete monomeric
Sn(dappc)Cl2units [H2dappc = 2,6-diacetylpyridine
bis(picolinoylhydrazone)] and H2O solvent molecules.
The Sn atom has a slightly distorted seven-coordinate
pentagonal bipyramidal environment, being bonded to
two O and three N atoms of the hydrazone molecule in
the pentagonal base and to two C1 atoms in the axial
positions.
