Abstract

This study reports the hydrothermal synthesis of a novel series of twelve coordination compounds, namely, {[Cd(-Hnbtc)(H2O)4]H2O}n (1), [Zn2(-Hnbtc)2(phen)2]2H2O (2), [Zn(Hnbtc)(phen)2(H2O)]4.5H2O (3), [Ni(Hnbtc)(phen)2(H2O)]6H2O (4), [Zn2(-Hnbtc)2(2,2-bipy)2]2H2O (5), [Cd3(5-nbtc)(6-nbtc)(2,2-bipy)2(H2O)]n (6), {[Zn3(3-nbtc)2(phen)3(H2O)2]4H2O} (7), [Co(H2O)6][Co2(nbtc)2(-4,4-bipy)(4,4-bipy)2(H2O)6]8H2O (8), {[Ni3(4-nbtc)2(-4,4-bipy)2.5(-H2O)(H2O)3]4H2O}n (9), {[Cd2(4-nbtc)(-OH)(2,2-bipy)2]H2O}n (10), [Cd2(4-nbtc)(-OH)(phen)2(H2O)]n (11), and {[Zn2(5-nbtc)(3-OH)(-4,4-bipy)]4,4-bipyH2O}n (12), which are derived from 3-nitro-biphenyl-2,4,4-tricarboxylic acid (H3nbtc) as a virtually unexplored building block.
