Reversible single-crystal to single-crystal phase transformation between a new Werner clathrate and its apohost.

ABSTRACT: In this work, we report the synthesis and structural characterisation of the ligand 2-(pyridin-3-yl)-benzo[de]isoquinoline-1,3(2H)-dione, 5, its isostructural Werner complexes ML₄(NCS)₂ (L = 5; M = Co(II) and Ni(II)), and five clathrates with three aromatic guests, ML₄(NCS)₂·2G (M = Co(II) and Ni(II), G = nitrobenzene (NB); M = Co, G = 1,2-dichlorobenzene (1,2-DCB); M = Co(II) and Ni(II), G = o-xylene (OX)). 5 was prepared in high yield by condensation in the solid-state (C³S³, Cocrystal Controlled Solid-State Synthesis). The Werner complexes ML₄(NCS)₂ (M = Co(II) and Ni(II)) (apohosts) were prepared by reacting M(NCS)₂ (M = Co(II) and Ni(II)) and 5 in 1-butanol at 60 °C
