Graphical Abstract
Support framework: Post-synthesis modification of an interpenetrating Zn-based chiral metal–organic framework with Ti(OiPr)4 results in a Lewis acidic catalyst (see picture; gray C, white H, red O, green Ti) with modest enantioselectivity in the asymmetric addition of diethylzinc to aldehydes. The Ti(OiPr)4-treated framework contains single-crystal to single-crystal cross-linking of the two interpenetrating networks.

- 15The Ti content (Ti/Zn=0.42) determined by the ICP-MS analysis is slightly higher than that determined from the X-ray structure (Ti/Zn=0.25), thus suggesting that there might be some disordered, unreacted Ti(OiPr)4 in the open channels of Ti-2.
