Sb and Sb found in [K(18-crown-6)][Sb] [Sb{Mo(CO)}]·2en: two missing family members.

Reaction of KMnSb and CHMo(CO) produced Sb and Sb found in [K(18-crown-6)][Sb][Sb{Mo(CO)}]·2en (1·2en) adding two new family members for antimony polyanions. The unusually short Sb-Sb bond in the Sb subunits of 1 reveals the formation of the second doubly bonded diatomic anion between heavy elements following Bi, and the first example of such doubly bonded anions stabilized by metal carbonyl groups.

[Ge{M(CO)}]: electrophilic addition of M(CO) and [E] Zintl anions (M = Cr, Mo, W).

Nucleophilic substitution reactions of KGe and M(CO) produced [Ge{M(CO)}] (M = Cr, 1a; Mo, 2a; W, 3a). The electrophilic addition of M(CO) and [Ge] occurred at the three capping sites to form almost perfect tricapped trigonal prismatic 1a-3a with crystallographic C symmetry.

Counterion-induced crystallization of intermetalloid Matryoshka clusters [Sb@Pd@Sb].

Two intermetalloid Matryoshka cluster anions [Sb@Pd@Sb] obtained from the reaction of KSb and Pd(PPh) were isolated as [K(2,2,2-cryptand)] and [K(18-crown-6)] salt, respectively, and characterized by X-ray crystallography, EPR measurement and DFT theoretical calculations.

Intercalation of Varied Sulfonates into a Layered MOC: Confinement-Caused Tunable Luminescence and Novel Properties.

The pores/channels of porous 3D metal-organic frameworks (MOFs) have been widely applied to incorporate gas, solvent, or organic molecules. On the contrary, the utilization of the interlamellar void of layered metal-organic complexes (MOCs) remains underappreciated, although it is more flexible and available to accommodate molecules with different sizes. In this work, diverse sulfonates have been intercalated purposely into an identical layered MOC, which constructed various novel intercalation compounds possessing fluorescent, white-light emitting, photochromic, homochiral, or nonlinear optical (NLO) properties.

Crystalline hybrid solid materials of palladium and decamethylcucurbit[5]uril as recoverable precatalysts for Heck cross-coupling reactions.

A series of MPdMe10 CB[5] (M=Li, Na, K, Rb, and Cs; Me10 CB[5]=decamethylcucurbit[5]uril) hybrid solid materials have been successfully synthesized for the first time through a simple diffusion method. These as-prepared hybrid solids have been applied as phosphine-free precatalysts for Heck cross-coupling reactions with excellent catalytic performance and good recyclability. In the processes of the catalytic reactions, the activated Pd(II) species were released from the crystalline hybrid precatalysts and transformed into catalytically active Pd nanoparticles, which have been demonstrated as key to carry on the catalytic reactions for the recoverable precatalysts MPdMe10 CB[5] (M=K, Rb, and Cs).
