The Sn(IV) atom in the title compound, 2[Sn(CH(3))(2)(C(6)H(5))Cl(H(2)O)]·C(10)H(20)O(5), exists in a trans-C(3)SnClO trigonal bipyramidal geometry in which the organo substituents occupy the equatorial sites. The coordinated water mol-ecule forms two hydrogen bonds to the 15-crown-5 mol-ecule, which is disordered about a center of inversion.

We present the synthesis and characterization of (15-crown-5)BiI3 (1) ⋅ 0.5TIE (2), a halogen bonded adduct with tetraiodoethylene (TIE), typical bond donor. Single crystal structure analysis 2 suggests bonding interaction between crown ether complex TIE. The two compounds’ thermal, optical vibrational properties are investigated in comparison, differences pointing towards notable building bloc...

A general and versatile molecular design for host molecules was proposed based on the structural motif of antibodies. A water-soluble potassium sensor was developed by this molecular design, which consists of three functional regions, benzo-15-crown-5 ether, DNA, and pyrene as guest-binding, dimerising, and signaling sites, respectively. The molecular sensor emitted the monomer fluorescence of ...
