چکیده
The title compound, 2C(4)H(12)N(2) (2+)·C(10)H(2)O(8) (4-)·6H(2)O or (pipzH(2))(2)(btc)·6H(2)O, was formed from the reaction between benzene-1,2,4,5-tetra-carboxylic acid (btcH(4)) as a proton donor and piperazine (pipz) as a proton acceptor. A variety of O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, as well as C-H⋯π inter-actions, are present in the crystal structure. Two water O atoms are each disordered over two positions; for both the site occupany factors are ca 0.66 and 0.34.

In the crystal of the title hydrated molecular salt, 2C(3)H(12)N(2) (2+)·C(10)H(2)O(8) (4-)·2H(2)O, the packing is stabilized by extensive N-H⋯O and O-H⋯O hydrogen-bonding inter-actions involving all three species, forming a supra-molecular three-dimensional structure. The tetraanion is generated by inversion.

In the title mol-ecule, C(30)H(42)N(6)O(2), the amide-substituted N atoms of the tetra-zine ring deviate from the approximate plane of the four other atoms in the ring by 0.457 (3) and 0.463 (3) Å, forming a boat conformation. The two benzene rings form a dihedral angle of 47.69 (9)°. Intra-molecular N-H⋯N and weak C-H⋯O hydrogen bonds are observed.
متن کاملAn air-stable bisboron complex: a practical bidentate Lewis acid catalyst
We report an air-stable bisboron complex as an efficient catalyst for the inverse electron-demand Diels-Alder (IEDDA) reaction of 1,2-diazine as well as 1,2,4,5-tetrazine. Its stability towards air and moisture was demonstrated by NMR studies enabling its application in organic transformations without glovebox. A one-pot procedure for its synthesis was developed starting from 1,2-bis(trimethyls...
