Abstract
A chiral-at-metal Ir(III) organometallic metallatecton was synthesised as a racemic mixture and as enantiopure complexes and combined with Cu(II) to afford a heterobimetallic (Ir,Cu) grid-type 2D coordination network.

A chiral-at-metal Ir(III) organometallic metallatecton was synthesised as a racemic mixture and as enantiopure complexes and combined with Cu(II) to afford a heterobimetallic (Ir,Cu) grid-type 2D coordination network
The design and formation of chiral-at-metal coordination networks based on chiral octahedral tris-chelate metallatectons remains a challenge
The chiral metallatecton is based on an achiral bipyridyl chelate bearing two peripheral monodentate pyridyl coordinating sites
Summary
A chiral-at-metal Ir(III) organometallic metallatecton was synthesised as a racemic mixture and as enantiopure complexes and combined with Cu(II) to afford a heterobimetallic (Ir,Cu) grid-type 2D coordination network. We report the synthesis and characterisation in solution and in the solid state of an unprecedented cyclometallated Ir(III) complex-based metallatecton [Ir(ppy)2(1)][PF6] as a racemic mixture of both L and D enantiomers, rac-[Ir(ppy)2(1)][PF6], and as enantiopure L (L-[Ir(ppy)2(1)][PF6]) or D (D-[Ir(ppy)2(1)][PF6]) complexes (Scheme 1). We describe the formation of a heterometallic (Cu,Ir) 2D grid-type coordination network resulting from the combination of rac-[Ir(ppy)2(1)][PF6] and [Cu(CH3CN)4][BF4].
