“…Squarate acts as a bridge between two or more metal atoms in mono-or polydentate coordination modes with first row transition metal ions [6,7]. It coordinates to Fe(II), Fe(III), Ni(II) and Cu(II) complexes in a -1,3 fashion, giving binuclear [8][9][10][11] and chain structures [12,13], whereas the -1,2 coordination mode has been reported for binuclear and chain complexes of Cu(II) and Pd(II) [14,15]. The squarate anion, with Cu(II) and Ni(II), is a tetradentate ligand forming polynuclear compounds [16].…”

“…Squarate acts as a bridge between two or more metal atoms in mono-or polydentate coordination modes when acting as a ligand towards first row transition metal ions [8,9]. It coordinates to Fe(II), Fe(III), Ni(II) and Cu(II) complexes in a l-1,3 fashion, giving binuclear [10][11][12] and chain structures [13,14], whereas the l-1,2 coordination mode has been reported for binuclear and chain complexes of Cu(II) and Pd(II) [15,16]. It is also observed that the squarate anion, with Cu(II) and Ni(II), acts as a tetramonodentate ligand and forms polynuclear compounds [17].…”

“…En la distancia Pd-N2 obtenemos un valor de 2.154 Å que es ligeramente mayor que otros valores encontrados en CSD para un enlace Pd-Piperidina. En todos los casos, en trans a la piperidina hay un átomo de nitrógeno, y los valores más cercanos al aquí encontrado son los publicados por Crispini et al 52 (2.106 y 2.105 Å). Aquí se presentan otros ejemplos tangibles de la influencia trans ya descrita por Clark (Ver página 93).…”

“…El valor para los dos enlaces Pd-N (Pip) (Pd-N1 y Pd-N2) es un poco más corto que el valor descrito por Crispini para sus compuestos. 52 El valor para Pd-Cl 1 coincide con valores de la bibliografía. Los valores de las distancias de enlace en la piperidina coinciden con valores encontrados en la bibliografía para enlaces C-C y C-N. 102 Ángulos del enlace (°) [ Continuando con los estudios de reactividad de este tipo de complejos, se planteó la posibilidad de estudiar metilaciones sobre el ligando coordinado utilizando reactivos nucleófilos.…”
