چکیده

In the title compound, [Hf(C(9)H(6)NO)(4)]·2C(7)H(8), the hafnium metal centre is coordinated by four N,O-donating bidentate quinolin-8-olate ligands arranged to give a square-anti-prismatic coordination polyhedron with a slightly distorted dodeca-hedral geometry. The average Hf-O and Hf-N distances are 2.096 (3) and 2.398 (3) Å, respectively, and the average O-Hf-N bite angle is 70.99 (11)°. The crystal packing is controlled by π-π inter-actions between quinoline ligands of neighbouring mol-ecules and hydrogen-bonding inter-actions. The inter-planar distances vary between 3.138 (1) and 3.208 (2) Å, while the centroid-centroid distances range from 3.576 (1) to 4.074 (1) Å.

In the reaction of 8-hy-droxy-quinoline, 2-methyl-8-hy-droxy-quinoline and stannic chloride, the 2-methyl-8-hy-droxy-quinoline is protonated, yielding the disolvated title salt, (C(10)H(10)NO)[SnCl(4)(C(9)H(6)NO)]·2CH(3)OH. The Sn(IV) atom in the anion is N,O-chelated by the hy-droxy-quinolinate in a cis-SnNOCl(4) octa-hedral geometry. In the crystal, the cation, anion and solvent mol-ecules ar...
