Two polymorphs of a lead(II) complex with 8-hydroxy-2-methylquinoline and thiocyanate
Artikel i vetenskaplig tidskrift, 2010

Two distinct polymorphs of bis(μ2-methylquinolin-8-olato)-κ3N,O:O;κ3O:N,O-bis[(isothiocyanato-κN)lead(II)], [Pb2(C10H8NO)2(NCS)2], (I), forming dinuclear complexes from a methanolic solution containing lead(II) nitrate, 2-methylquinolin-8-ol (M-Hq) and KSCN, crystallized concomitantly as colourless prisms [form (Ia)] and long thin colourless needles [form (Ib)]. In both cases, the complexes lie across a centre of inversion. The polymorphs differ substantially in their conformation and in their interactions, viz. Pb...S and π-π for form (Ia) and Pb...S, Pb...π and C-H...π for form (Ib).
